Mathematical Functions
Mathematical functions provide standard algebraic and trigonometric
functions for use in expressions. The available mathematical functions are
shown in the table below.
All mathematical functions are read-only—they can be used within an
expression to perform the desired function, but they cannot be assigned a
value. Each mathematical function is explained below.
