Description

• 

The function parity computes the parity of an expression, by assuming that unspecified exponents are integers. Given n is an integer, pnmod2=p. For unassigned names, the function parity returns the name.

• 

It is with the parity function that defform recognizes certain names as even or odd.

• 

The command with(difforms,parity) allows the use of the abbreviated form of this command.
