Documentation:
Complex functions have been defined that help determine how to manipulated specific values. These functions can be nested together to form complex statements. Each function is designed to work on a specific type of data. If the data being worked on is not of the correct type, a cast should be attempted before throwing an error. For example, if a concat function includes a registry component that returns an integer, then the integer should be cast as a string in order to work with the concat function. Note that if the operation being applied to the variable by the calling entity is "pattern match", then all the functions are performed before the regular expression is evaluated. In short, the variable would produce a value as normal and then any pattern match operation would be performed. Please refer to the description of a specific function for more details about it.
