Boolean

see also: Etymology of Boolean

A Boolean in Logical and data-processing Programmation is a type of Variable in two states. The variables of this type are thus either in a true state or with the state false (in English true and false ).

Generally the conditions are of Boolean type, because they require a binary answer of the type yes or not .

button inserted : a Boolean condition

lit light : a Boolean variable

----

If button inserted

then lit light = true

if not lit light = false

Certain languages use the bit to represent the Boolean ones: thus a 0 will represent the value false and a 1 will represent the value true (or the reverse, according to conventions). Other languages will prefer to use English TRUE (true) and FALSE (false) traditionally in capital letters.
