Floating points, known as floats for short, are commonly referred to as decimal numbers. This type of data is stored differently in computer memory than integers and therefore must be differentiated in the code. Functions such as CEIL and FLOOR can be used to round numbers depending on whether you need floats or integers. "Numbers part two: Floating points" explains how different types of numeric values can be used to make calculations in PHP and MySQL.
