FUNCTION
<<infinity>>, <<infinityf>>---representation of infinity
INDEX
infinity
INDEX
infinityf
ANSI_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.
QUICKREF
infinity - pure
