fpow

Raise one number to the power of another, according to IEEE 754

&reftitle.description; `float` `fpow` `float` `num` `float` `exponent`

Returns the floating point result of raising `num` to the power of `exponent`. If `num` is zero and `exponent` is less than zero, then `INF` is returned.

&reftitle.parameters;

`num`

- The base to use.

`exponent`

- The exponent.

&reftitle.returnvalues;

Returns a `float` corresponding to `$num$exponent`.

### `fpow` example

    <?php
    var_dump(fpow(10, 2));
    var_dump(fpow(0, -3));
    var_dump(fpow(-1, 5.5));
    ?>

&example.outputs;

    float(100)
    float(INF)
    float(NAN)
