How to get whole and decimal part of a number?

Question

Given, say, 1.25 - how do I get \"1\" and .\"25\" parts of this number?

I need to check if the decimal part is .0, .25, .5, or .75.

Answer 1

This code will split it up for you:

list($whole, $decimal) = explode('.', $your_number);

where $whole is the whole number and $decimal will have the digits after the decimal point.
