This book describes how to use the Rexx Math functions. The section entitled Function Reference lists (in alphabetic order) all of the Rexx Math functions that you can call. Each function is on its own page. The name of the function is listed first. Listed below is its syntax (ie, what arguments you pass to it and what it returns), as well as examples of its use. Arguments that you must supply are in blue, and arguments that you may omit are in red.
