Maple Constants

Description

 • The numeric constants in Maple are integers, fractions, floating-point numbers, and complex numbers whose real and imaginary parts are any of these types of numbers.
 • The global variable constants is an expression sequence of all names which are initially known as symbolic constants in Maple.  These are:

 false gamma infinity true Catalan FAIL Pi

 • The values undefined and Float(undefined) do not appear on this list because neither is a constant.
 • The user can declare any symbol other than undefined to be a constant by appending it to constants.
 • The expression (-1)^(1/2) is implemented as Complex(1).
 • More generally, a Maple expression is of type constant if it is an unevaluated function with all arguments of type constant, or a sum, product, or power with all operands of type constant.
