Better wording: The parity of x o. y as a function (odd or even) is the same as the parity of x as a number. ----- Original Message ----- From: Roger Hui <[EMAIL PROTECTED]> Date: Friday, February 2, 2007 1:00 pm Subject: Re: [Jprogramming] What is the name for x in x $. y ? I guess "function code" is as good a description as any. Usually there is no deep meaning behind the particular value of a function code. Sometimes there is a small mnemonic value: x o. y is an odd or even function, the same as the parity of x . (-x) p: y is the inverse of x p: y, if there is an inverse. Likewise x s: y . x u: y should have been made to follow this pattern (but does not). ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
