A floating point number is a number with a set number of digits where the decimal point can be placed anywhere, as 10.5, 3.14, or -623.1231. This allows numbers of different precision to be stored in the same amount of data. Numbers which do not have decimal points are called integers. The computing of floating point numbers is very important for image processing and 3D video games, so the processors on video cards are specially designed to compute floating point numbers quickly.
