pow
POW(3) 1 POW(3)pow - Exponential expressionSYNOPSIS
number pow (number $base, number $exp)

PARAMETERS
o $base
- The base to use
o $exp

will be returned with integer type, otherwise it will be returned as a float.
EXAMPLES
Example #1
Some examples of pow(3)
<?php
var_dump(pow(2, 8)); // int(256)
echo pow(-1, 20); // 1
echo pow(0, 0); // 1
echo pow(-1, 5.5); // PHP >4.0.6 NAN
echo pow(-1, 5.5); // PHP <=4.0.6 1.#IND
