necessary to #include "float.h" or another system-dependent header
file.
The values returned for NaNs may be signaling NaNs on some systems,
since the rules for distinguishing signaling from quiet NaNs are
system-dependent. You can easily fix this by suitably modifying the
ULto* routines in strtor*.c.
Source file strtodnrp.c gives a strtod that does not require 53-bit
rounding precision on systems (such as Intel IA32 systems) that may
suffer double rounding due to use of extended-precision registers.
For some conversions this variant of strtod is less efficient than the
one in strtod.c when the latter is run with 53-bit rounding precision.
The values that the strto* routines return for NaNs are determined by
gd_qnan.h, which the makefile generates by running the program whose
source is qnan.c. Note that the rules for distinguishing signaling
from quiet NaNs are system-dependent. For cross-compilation, you need
to determine arith.h and gd_qnan.h suitably, e.g., using the
arithmetic of the target machine.
C99's hexadecimal floating-point constants are recognized by the
strto* routines (but this feature has not yet been heavily tested).
Compiling with NO_HEX_FP #defined disables this feature.
The strto* routines do not (yet) recognize C99's NaN(...) syntax; the
strto* routines simply regard '(' as the first unprocessed input
character.
When compiled with -DINFNAN_CHECK, the strto* routines recognize C99's
NaN and Infinity syntax. Moreover, unless No_Hex_NaN is #defined, the
strto* routines also recognize C99's NaN(...) syntax: they accept
(case insensitively) strings of the form NaN(x), where x is a string
of hexadecimal digits and spaces; if there is only one string of
hexadecimal digits, it is taken for the fraction bits of the resulting
NaN; if there are two or more strings of hexadecimal digits, each
string is assigned to the next available sequence of 32-bit words of
fractions bits (starting with the most significant), right-aligned in
each sequence.
For binary -> decimal conversions, I've provided just one family
