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 maintained as a Texinfo manual. If info and are properly installed at your site, the command
