Mathematical Functions

 

The mathematical functions built into EES are listed below in alphabetical order.  All of the functions (except PI, TABLENAME$, and TABLERUN#) require one or more arguments that must be enclosed in parentheses and separated with commas.  The argument may be a numerical value, a variable name, or an algebraic expression involving values and variables.  Functions that require two or more arguments can accept arguments in array range notation, e.g., X[1..5].
