Expressions in Siebel eScript
An expression is a collection of two or more terms that perform a mathematical or logical operation. The terms are usually either variables or functions that are combined with an operator to evaluate to a string or numeric result. You use expressions to perform calculations, manipulate variables, or concatenate strings.
Expressions are evaluated according to order of precedence. Use parentheses to override the default order of precedence.
The order of precedence (from high to low) for the operators is:
- Arithmetic operators
- Comparison operators
- Logical operators
