2013-06-03BZ #15536: Fix ulp for 128-bit IBM long double.Carlos O'Donell1-11/+26
In 128-bit IBM long double the precision of the type decreases as you approach subnormal numbers, equaling that of a double for subnormal numbers. Therefore adjust the computation in ulp to use 2^(MIN_EXP - MANT_DIG) which is correct for FP_SUBNORMAL for all types.

2013-05-24Correctly compute ulp near zero.Carlos O'Donell1-48/+93
The current value used for ulp near zero is wrong, and this commit fixes it such that ulp(0) is the smallest subnormal value nearest to zero, which makes the most sense for testing values near zero. Note that this is not what Java does; they use the nearest normal value, which is less accurate than what we want for glibc. Note that there is no correct implementation of ulp since there is no strict mathmatical definition that is accepted by all groups using IEEE 754. Previously with the large ulp values near zero there were tests that previously passed, but were in fact billions of ulp away from the precise answer. With this commit we now need to disable one of the cpow tests which is revealed to be inaccurate (bug 14473). --- 2013-05-24 Carlos O'Donell <carlos@redhat.com> * math/libm-test.inc (MAX_EXP): Define. (ULPDIFF): Define. (ulp): New function. (check_float_internal): Use ULPDIFF. (cpow_test): Disable failing test. (check_ulp): Test ulp() implemetnation. (main): Call check_ulp before starting tests.
