| /glibc-2.36/ChangeLog.old/ |
| D | ChangeLog.1 | 1154 * math/math.h [__USE_GNU]: #include <nan.h> to get NAN value.
1265 * sysdeps/generic/frexp.c [NAN]: If VALUE is infinite, return NAN.
1266 If VALUE is NAN, set errno to EDOM and return VALUE.
1631 * sysdeps/ieee754/__drem.c: Return NAN if Y is zero.
1637 * sysdeps/ieee754/fl.h: Fixed NAN and HUGE_VAL bit patterns; added
2073 * sysdeps/ieee754/__infnan.c: Include <float.h> and use NAN macro
2521 (NAN): New macro for an IEEE NaN, done like HUGE_VAL.
|
| D | ChangeLog.7 | 13 * sysdeps/libm-ieee754/s_nanl.c (__nanl): Use NAN instead of
16 * sysdeps/libm-ieee754/s_nanf.c (__nanf): Use NAN instead of
40 * sysdeps/ieee754/bits/nan.h: Define NAN as of type float.
8546 * sysdeps/ieee754/nan.h: Similar for NAN. Add NANF and NANL.
11979 * sysdeps/libm-ieee754/k_standard.c: Return NAN for libm not in
12880 or inf depending on case of specifier. Same for NaN where NAN
12891 * stdlib/strtod.c: Change to recognize INF, INFINITY, NAN, and
12892 NAN(...).
|
| D | ChangeLog.14 | 999 * sysdeps/ieee754/bits/nan.h (NAN): Use __builtin_nanf.
1000 * sysdeps/mips/bits/nan.h (NAN): Likewise.
