From 5be4316ea2f4bb8a59a7861b5dd3c5ebfea6a715 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Mon, 8 Mar 1999 21:41:47 +0000 Subject: Update. 1999-03-09 Andreas Schwab * 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 * stdio-common/printf_fphex.c (__printf_fphex): Print no decimal point if the precision is zero, even if the mantissa is non-zero. --- sysdeps/generic/strtold.c | 41 +++++++++++++++++++++++++++++++++++++++++ sysdeps/m68k/strtold.c | 2 ++ 2 files changed, 43 insertions(+) create mode 100644 sysdeps/generic/strtold.c create mode 100644 sysdeps/m68k/strtold.c (limited to 'sysdeps') diff --git a/sysdeps/generic/strtold.c b/sysdeps/generic/strtold.c new file mode 100644 index 0000000000..f1bb2f1c0d --- /dev/null +++ b/sysdeps/generic/strtold.c @@ -0,0 +1,41 @@ +#include + +#ifndef __NO_LONG_DOUBLE_MATH +/* The actual implementation for all floating point sizes is in strtod.c. + These macros tell it to produce the `long double' version, `strtold'. */ + +# define FLOAT long double +# define FLT LDBL +# ifdef USE_IN_EXTENDED_LOCALE_MODEL +# define STRTOF __strtold_l +# else +# define STRTOF strtold +# endif +# define MPN2FLOAT __mpn_construct_long_double +# define FLOAT_HUGE_VAL HUGE_VALL +# define SET_MANTISSA(flt, mant) \ + do { union ieee854_long_double u; \ + u.d = (flt); \ + if ((mant & 0x7fffffffffffffffULL) == 0) \ + mant = 0x4000000000000000ULL; \ + u.ieee.mantissa0 = (((mant) >> 32) & 0x7fffffff) | 0x80000000; \ + u.ieee.mantissa1 = (mant) & 0xffffffff; \ + (flt) = u.d; \ + } while (0) + +# include "strtod.c" +#else +# include +/* There is no `long double' type, use the `double' implementations. */ +long double +__strtold_internal (const char *nptr, char **endptr, int group) +{ + return __strtod_internal (nptr, endptr, group); +} + +long double +strtold (const char *nptr, char **endptr) +{ + return __strtod_internal (nptr, endptr, 0); +} +#endif diff --git a/sysdeps/m68k/strtold.c b/sysdeps/m68k/strtold.c new file mode 100644 index 0000000000..dd7fbce195 --- /dev/null +++ b/sysdeps/m68k/strtold.c @@ -0,0 +1,2 @@ +#define DENORM_EXP (MIN_EXP - 1) +#include -- cgit v1.2.3
