This file has to be included by a master file that defines: Makros: FUNC(function): converts general function name (like cos) to name with correct suffix (e.g. cosl or cosf) MATHCONST(x): like FUNC but for constants (e.g convert 0.0 to 0.0L) MATHTYPE: floating point type to test TEST_MSG: informal message to be displayed CHOOSE(Clongdouble,Cdouble,Cfloat): chooses one of the parameters as epsilon for testing equality PRINTF_EXPR Floating point conversion specification to print a variable of type MATHTYPE with printf. PRINTF_EXPR just contains the specifier, not the percent and width arguments, e.g. "f" */ /* This program isn't finished yet. It has tests for: acos, acosh, asin, asinh, atan, atan2, atanh, cbrt, ceil, copysign, cos, cosh, erf, erfc, exp, exp2, expm1, fabs, fdim, floor, fmin, fmax, fmod, fpclassify, frexp, gamma, hypot, ilogb, isfinite, isinf, isnan, isnormal, ldexp, lgamma, log, log10, log1p, log2, logb, modf, nearbyint, nextafter, pow, remainder, remquo, rint, lrint, llrint, round, lround, llround, scalb, scalbn, signbit, sin, sincos, sinh, sqrt, tan, tanh, trunc and for the following complex math functions: cacos, cacosh, casin, casinh, catan, catanh, ccos, ccosh, cexp, clog, cpow, csin, csinh, csqrt, ctanh. At the moment the following functions aren't tested: cabs, carg, conj, cproj, cimag, creal, ctan, drem, j0, j1, jn, y0, y1, yn, significand, nan, comparison macros (isless,isgreater,...). The routines using random variables are still under construction. I don't like it the way it's working now and will change it. Parameter handling is primitive in the moment: --verbose=[0..4] for different levels of output: 0: only error count 1: basic report on failed tests (default) 2: full report on failed tests 3: full report on failed and passed tests 4: additional report on exceptions -v for full output (equals --verbose=4) -s,--silent outputs only the error count (equals --verbose=0) */ /* "Philosophy": This suite tests the correct implementation of mathematical functions in libm. Some simple, specific parameters are tested for correctness. Handling of specific inputs (e.g. infinity, not-a-number) is also tested. Correct handling of exceptions is checked against. These implemented tests should check all cases that are specified in ISO C 9X. Exception testing: At the moment only divide-by-zero and invalid exceptions are tested. Overflow/underflow and inexact exceptions aren't checked at the moment. NaN values: There exist signalling and quiet NaNs. This implementation only uses signalling NaN as parameter but does not differenciate between the two kinds of NaNs as result. Inline functions: Inlining functions should give an improvement in speed - but not in precission. The inlined functions return reasonable values for a reasonable range of input values. The result is not necessarily correct for all values and exceptions are not correctly raised in all cases. Problematic input and return values are infinity, not-a-number and minus zero. This suite therefore does not check these specific inputs and the exception handling for inlined mathematical functions - just the "reasonable" values are checked. Beware: The tests might fail for any of the following reasons: - Tests are wrong - Functions are wrong - Floating Point Unit not working properly - Compiler has errors With e.g. gcc 2.7.2.2 the test for cexp fails because of a compiler error. */ #ifndef _GNU_SOURCE # define _GNU_SOURCE #endif #include #include #include #include #include #include #include #include /* Possible exceptions */ #define NO_EXCEPTION 0x0 #define INVALID_EXCEPTION 0x1 #define DIVIDE_BY_ZERO_EXCEPTION 0x2 #define PRINT 1 #define NO_PRINT 0 /* Various constants (we must supply them precalculated for accuracy). */ #define M_PI_6 .52359877559829887308L static int noErrors;
