Mathematical Representation Problems

[Anon]

Hi all,

I'm really sorry but I'm not able to access the PHP Manual online due to some problems.

I wonder how can I represent the expression (x to the power of n) in php ?
I tried $x² but I received an error.

Also how can I declare all of my variables to be double instead of integer.

Hi,

from the PHP manual:

pow (PHP 3, PHP 4 >= 4.0.0)

pow -- Exponential expression
Description
number pow ( number base, number exp)

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.
