16 FUNCTION
17 <<pow10>>, <<pow10f>>---base 10 power functions
18 INDEX
19 pow10
20 INDEX
21 pow10f
22
23 SYNOPSIS
24 #include <math.h>
25 double pow10(double <[x]>);
26 float pow10f(float <[x]>);
27
28 DESCRIPTION
29 <<pow10>> and <<pow10f>> calculate 10 ^ <[x]>, that is,
30 @ifnottex
31 10 raised to the power <[x]>.
32 @end ifnottex
33 @tex
34 $10^x$
35 @end tex
36
37 RETURNS
38 On success, <<pow10>> and <<pow10f>> return the calculated value.
39 If the result underflows, the returned value is <<0>>. If the
40 result overflows, the returned value is <<HUGE_VAL>>. In
41 either case, <<errno>> is set to <<ERANGE>>.
42
43 PORTABILITY
44 <<pow10>> and <<pow10f>> are GNU extensions.
