2020-03-26Fix spurious underflow exceptions for Bessel functions for double(from glibc ↵Joseph S. Myers4-9/+13
bug 14155) This fix comes from glibc, from files which originated from the same place as the newlib files. Those files in glibc carry the same license as the newlib files. Bug 14155 is spurious underflow exceptions from Bessel functions for large arguments. (The correct results for large x are roughly constant * sin or cos (x + constant) / sqrt (x), so no underflow exceptions should occur based on the final result.) There are various places underflows may occur in the intermediate calculations that cause the failures listed in that bug. This patch fixes problems for the double version where underflows occur in calculating the intermediate functions P and Q (in particular, x**-12 gets computed while calculating Q). Appropriate approximations are used for P and Q for arguments at least 0x1p28 and above to avoid the underflows. For sufficiently large x - 0x1p129 and above - the code already has a cut-off to avoid calculating P and Q at all, which means the approximations -0.125 / x and 0.375 / x can't themselves cause underflows calculating Q. This cut-off is heuristically reasonable for the point beyond which Q can be neglected (based on expecting around 0x1p-64 to be the least absolute value of sin or cos for large arguments representable in double). The float versions use a cut-off 0x1p17, which is less heuristically justifiable but should still only affect values near zeroes of the Bessel functions where these implementations are intrinsically inaccurate anyway (bugs 14469-14472), and should serve to avoid underflows (the float underflow for jn in bug 14155 probably comes from the recurrence to compute jn). ldbl-96 uses 0x1p129, which may not really be enough heuristically (0x1p143 or so might be safer - 143 = 64 + 79, number of mantissa bits plus total number of significant bits in representation) but again should avoid underflows and only affect values where the code is substantially inaccurate anyway. ldbl-128 and ldbl-128ibm share a completely different implementation with no such cut-off, which I propose to fix separately.

2020-03-19Fix hypotf missing mask in hi+lo decompositionFabian Schriever1-2/+2
Add the missing mask for the decomposition of hi+lo which caused some errors of 1-2 ULP. This change is taken over from FreeBSD: https://github.com/freebsd/freebsd/commit/95436ce20dab5a34ba46373410b96411b1734578 Additionally I've removed some variable assignments which were never read before being overwritten again in the next 2 lines.
2020-03-18Fix for k_tan.c specific inputsFabian Schriever1-8/+21
This fix for k_tan.c is a copy from fdlibm version 5.3 (see also http://www.netlib.org/fdlibm/readme), adjusted to use the macros available in newlib (SET_LOW_WORD). This fix reduces the ULP error of the value shown in the fdlibm readme (tan(1.7765241907548024E+269)) to 0.45 (thereby reducing the error by 1). This issue only happens for large numbers that get reduced by the range reduction to a value smaller in magnitude than 2^-28, that is also reduced an uneven number of times. This seems rather unlikely given that one ULP is (much) larger than 2^-28 for the values that may cause an issue. Although given the sheer number of values a double can represent, it is still possible that there are more affected values, finding them however will be quite hard, if not impossible. We also took a look at how another library (libm in FreeBSD) handles the issue: In FreeBSD the complete if branch which checks for values smaller than 2^-28 (or rather 2^-27, another change done by FreeBSD) is moved out of the kernel function and into the external function. This means that the value that gets checked for this condition is the unreduced value. Therefore the input value which caused a problem in the fdlibm/newlib kernel tan will run through the full polynomial, including the careful calculation of -1/(x+r). So the difference is really whether r or y is used. r = y + p with p being the result of the polynomial with 1/3*x^3 being the largest (and magnitude defining) value. With x being <2^-27 we therefore know that p is smaller than y (y has to be at least the size of the value of x last mantissa bit divided by 2, which is at least x*2^-51 for doubles) by enough to warrant saying that r ~ y. So we can conclude that the general implementation of this special case is the same, FreeBSD simply has a different philosophy on when to handle especially small numbers.
2020-03-09Fix error in exp in magnitude [2e-32,2e-28]Fabian Schriever2-2/+2
While testing the exp function we noticed some errors at the specified magnitude. Within this range the exp function returns the input value +1 as an output. We chose to run a test of 1m exponentially spaced values in the ranges [-2^-27,-2^-32] and [2^-32,2^-27] which showed 7603 and 3912 results with an error of >=0.5 ULP (compared with MPFR in 128 bit) with the highest being 0.56 ULP and 0.53 ULP. It's easy to fix by changing the magnitude at which the input value +1 is returned from <2^-28 to <2^-32 and using the polynomial instead. This reduces the number of results with an error of >=0.5 ULP to 485 and 479 in above tests, all of which are exactly 0.5 ULP. As we were already checking on exp we also took a look at expf. For expf the magnitude where the input value +1 is returned can be increased from <2^-28 to <2^-23 without accuracy loss for a slight performance improvement. To ensure this was the correct value we tested all values in the ranges [-2^-17,-2^-28] and [2^-28,2^-17] (~92.3m values each).
2020-03-03Fix error in float trig. function range reductionFabian Schriever1-1/+1
The single-precision trigonometric functions show rather high errors in specific ranges starting at about 30000 radians. For example the sinf procedure produces an error of 7626.55 ULP with the input 5.195880078125e+04 (0x474AF6CD) (compared with MPFR in 128bit precision). For the test we used 100k values evenly spaced in the range of [30k, 70k]. The issues are periodic at higher ranges. This error was introduced when the double precision range reduction was first converted to float. The shift by 8 bits always returns 0 as iq is never higher than 255. The fix reduces the error of the example above to 0.45 ULP, highest error within the test set fell to 1.31 ULP, which is not perfect, but still a significant improvement. Testing other previously erroneous ranges no longer show particularly large accuracy errors.
2020-03-02Fix error in powf for (-1.0, NaN) inputFabian Schriever1-1/+1

2020-02-14pow: fix pow(-1.0, NaN)Nicolas Brunie1-1/+1
I think I may have encountered a bug in the implementation of pow: pow(-1.0, NaN) returns 1.0 when it should return NaN. Because ix is used to check input vs 1.0 rather than hx, -1.0 is mistaken for 1.0
2019-01-23Use nanf() instead of nan() in single-precision float libm math functionsJozef Lawrynowicz4-4/+4

It uses a 2 KB lookup table, on aarch64 .text+.rodata size of libm.a is increased by 1703 bytes. The w_log.c wrapper is disabled since error handling is inline in the new code. New __HAVE_FAST_FMA and __HAVE_FAST_FMA_DEFAULT feature macros were added to enable selecting between the code path that uses fma and the one that does not. Targets supposed to set __HAVE_FAST_FMA_DEFAULT if they have single instruction fma and the compiler can actually inline it (gcc has __FP_FAST_FMA macro but that does not guarantee inlining with -fno-builtin-fma).

The new implementations are provided under !__OBSOLETE_MATH, they use ISO C99 code. There are several settings, with the default one the worst case error in nearest rounding mode is 0.509 ULP for exp and 0.507 ULP for exp2 when a multiply and add is contracted into an fma. They use a shared 2 KB lookup table, on aarch64 .text+.rodata size of libm.a is increased by 1868 bytes. The w_*.c wrappers are disabled for the new code as it takes care of error handling inline. The old exp2(x) code used to be just pow(2,x) so the speedup there is more significant. The file name has no special prefix to avoid any name collision with existing files.

2018-06-21Improve performance of sinf/cosf/sincosfWilco Dijkstra3-0/+7
Here is the correct patch with both filenames and int cast fixed: This patch is a complete rewrite of sinf, cosf and sincosf. The new version is significantly faster, as well as simple and accurate. The worst-case ULP is 0.56072, maximum relative error is 0.5303p-23 over all 4 billion inputs. In non-nearest rounding modes the error is 1ULP. The algorithm uses 3 main cases: small inputs which don't need argument reduction, small inputs which need a simple range reduction and large inputs requiring complex range reduction. The code uses approximate integer comparisons to quickly decide between these cases - on some targets this may be slow, so this can be configured to use floating point comparisons. The small range reducer uses a single reduction step to handle values up to 120.0. It is fastest on targets which support inlined round instructions. The large range reducer uses integer arithmetic for simplicity. It does a 32x96 bit multiply to compute a 64-bit modulo result. This is more than accurate enough to handle the worst-case cancellation for values close to an integer multiple of PI/4. It could be further optimized, however it is already much faster than necessary.

2017-10-13New expf, exp2f, logf, log2f and powf implementationsSzabolcs Nagy10-4/+77
Based on code from https://github.com/ARM-software/optimized-routines/ This patch adds a highly optimized generic implementation of expf, exp2f, logf, log2f and powf. The new functions are not only faster (6x for powf!), but are also smaller and more accurate. In order to achieve this, the algorithm uses double precision arithmetic for accuracy, avoids divisions and uses small table lookups to minimize the polynomials. Special cases are handled inline to avoid the unnecessary overhead of wrapper functions and set errno to POSIX requirements. The new functions are added under newlib/libm/common, but the old implementations are kept (in newlib/libm/math) for non-IEEE or pre-C99 systems. Targets can enable the new math code by defining __OBSOLETE_MATH_DEFAULT to 0 in newlib/libc/include/machine/ieeefp.h, users can override the default by defining __OBSOLETE_MATH. Currently the new code is enabled for AArch64 and AArch32 with VFP. Targets with a single precision FPU may still prefer the old implementation. libm.a size changes: arm: -1692 arm/thumb/v7-a/nofp: -878 arm/thumb/v7-a+fp/hard: -864 arm/thumb/v7-a+fp/softfp: -908 aarch64: -1476
