# 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.

see **Boolean Operators** on the [Operators] page for operators the produce and work with boolean values.

See Wikipedia:Boolean_Algebra for an in-depth definition and some theory discussion.

**inio:** None of the other primitive types have pages of their own, why should this? If it is worth keeping around, shouldn't it be 'bool' to match the UnrealScript variable type?

**Tarquin:** you could just put this material on to Wikipedia and link to Wikipedia:Boolean :D (but the original writer has to do this because of Wikipedia's GFDL.)
