Update.
1999-03-09 Andreas Schwab <schwab@issan.cs.uni-dortmund.de> * stdlib/strtod.c (round_and_return): Fix rounding of denormals. (DENORM_EXP): New define. Use it as the exponent for a denormal. * stdlib/strtold.c: Moved to ... * sysdeps/generic/strtold.c: ... here. * sysdeps/m68k/strtold.c: New file. 1999-03-09 Andreas Schwab <schwab@issan.cs.uni-dortmund.de> * stdio-common/printf_fphex.c (__printf_fphex): Print no decimal point if the precision is zero, even if the mantissa is non-zero.
