INFINITY(3) NEWLIB INFINITY(3)NAME
1.29 `infinity', `infinityf'-representation of infinity
SYNOPSIS
#include <math.h>
double infinity(void);
float infinityf(void);
DESCRIPTION
`infinity' and `infinityf' return the special number IEEE infinity in
double- and single-precision arithmetic respectively.
PORTABILITY
`infinity' and `infinityf' are neither standard C nor POSIX. C and
POSIX require macros HUGE_VAL and HUGE_VALF to be defined in math.h,
which Newlib defines to be infinities corresponding to these archaic
infinity() and infinityf() functions in floating-point implementations
which do have infinities.
SEE ALSO
infinity is part of the library. The full documentation for is main‐
tained as a Texinfo manual. If info and are properly installed at your
site, the command

will give you access to the complete manual.
