Functions

RATS offers a rich selection of functions for doing calculations, displaying information, programming complex tasks, and more. You can use these functions anywhere RATS expects an expression of the appropriate type. The syntax for all functions is:

name(argument1,argument2,...)

The left parenthesis must come immediately after the function name, with no spaces between the two.

Use the Function Wizard

RATS now includes a "Function Wizard", which provides an easy way to find and use the functions you need. To access the function wizard, just click on the toolbar icon, or select View—Standard Functions....
