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

	You can use the (non-ANSI) function <<matherr>> to specify
	error handling for these functions.

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.
