Boolean Operators

Boolean Operators perform various operations on the terms specified. There are several different types of operation available.

Symbol Type Name Description Example
?& Infix AND True if left and right terms are true a ?& b
?| Infix OR True if left or right terms are true a ?| b
?^ Infix XOR True if left or right terms, but not both, are true a ?^ b
?^ Prefix NOT Inverts the value of the term ?^ a
Type Casting
? Prefix Cast Converts the term to a Boolean ?a
! Prefix Inverse cast Converts the term to a Boolean, and inverts the value !a
Type Checking
is Infix IsType Checks if the value of the left term is of the type specified by the right term a is boolean

Each Operator will evaluate the terms provided as appropriate to the Operator value type - for instance, performing a boolean bitwise OR on two Numbers will convert the Numbers to Booleans first.
