Visual Basic (VB) Expressions

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 precedence order. Use parentheses to override the default precedence order.

The precedence order (from high to low) for the operators is:

• Numeric Operators
• String Operators
• Comparison Operators (Numeric and String)
• Logical Operators
