FUNCTION
<<pow10>>, <<pow10f>>---base 10 power functions
INDEX
pow10
INDEX
pow10f
SYNOPSIS
#include <math.h>
double pow10(double <[x]>);
float pow10f(float <[x]>);
DESCRIPTION
<<pow10>> and <<pow10f>> calculate 10 ^ <[x]>, that is,
@ifnottex
10 raised to the power <[x]>.
@end ifnottex
@tex
$10^x$
@end tex
RETURNS
On success, <<pow10>> and <<pow10f>> return the calculated value.
If the result underflows, the returned value is <<0>>. If the
result overflows, the returned value is <<HUGE_VAL>>. In
either case, <<errno>> is set to <<ERANGE>>.
PORTABILITY
<<pow10>> and <<pow10f>> are GNU extensions.
