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.
