# Legacy:Boolean

Named after its inventor, French mathematician George Boole, Boolean arithmetic is a small subset of discrete mathematics. Specifically, it is the study of systems in which a variable or expression may take on exactly one of two distinct values. Common definitions of these value pairs are: True/False, On/Off, and Yes/No. Boolean values are represented in UnrealScript with the 'bool' variable type.
