| FUNCTION |
| <<pow10>>, <<pow10f>>---exponential |
| INDEX |
| pow10 |
| INDEX |
| pow10f |
| |
| ANSI_SYNOPSIS |
| #include <math.h> |
| double pow10(double <[x]>); |
| float pow10f(float <[x]>); |
| |
| TRAD_SYNOPSIS |
| #include <math.h> |
| double pow10(<[x]>); |
| double <[x]>; |
| |
| float pow10f(<[x]>); |
| 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. |
