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
