[BZ #15425]
|
||||
* sysdeps/ieee754/dbl-64/e_exp.c: Include <float.h>.
|
||||
(__ieee754_exp): For possibly underflowing results, check size of
|
||||
result and force underflow exception if required.
|
||||
* math/auto-libm-test-in: Add more tests of exp.
|
||||
* math/auto-libm-test-out: Regenerated.
|
||||
* sysdeps/i386/fpu/libm-test-ulps: Update.
|
||||
* sysdeps/x86_64/fpu/libm-test-ulps: Likewise.
|
||||
|
||||
[BZ #16283]
|
||||
* math/w_exp2.c (__exp2): Handle a zero result as underflow.
|
||||
* math/w_exp2f.c (__exp2f): Likewise.
