Export - Maple Help

Logic

 Export
 express in terms of Logic package operators

 Calling Sequence Export(expr, {form})

Parameters

 expr - expression suitable for use by the Logic package form - expression where form=MOD2 or form=boolean

Description

 • The Export command transforms the expression $\mathrm{expr}$ into one of a specified type.

Available Conversions

 The following conversions are available (form must be one of these).
 • MOD2: The Boolean expression is converted to its equivalent modulo 2 format by mapping &and to multiplication, &xor to addition, true to $1$, and false to $0$.
 • boolean: Any Logic package operators present in the expression are replaced with the equivalent ternary logical operators, for example, and, or, and not.
