I'm in a bit of a pickle. I need to find out if a variable is a perfect square or not, and this needs to test for decimal numbers as well, such as 2.25. The thing is, the only function I've found in PHP is gmp_perfect_square() which isn't supported on my web server, and I don't know how to compile the GMP code into PHP on my windows box. So, how exactly would you go about finding out if something is a perfect square or not?
