Returns base
raised to the power of
exp
. If possible, this function will
return an integer.
If the power cannot be computed, a warning will be issued, and pow() will return FALSE. Since PHP 4.2.0 pow() doesn't issue any warning.
Note: PHP cannot handle negative
base
s.
Warning |
In PHP 4.0.6 and earlier pow() always returned a float, and did not issue warnings. |
