Formula Language
This section documents the formula language.
Formula Language Rules
Formula language provides syntax and @functions for evaluating constants and variables, and for performing simple logic. Variables can be fields in Notes® documents or temporary variables (also called temporary fields) used only for the immediate formula.
Using operators
Operators assign values, modify values, and combine existing values into new values. The following sections describe:
Order of evaluation for operations
The values involved in an operation must be of the same data type. Operations occur in the following order:

Order of evaluation for operations

The values involved in an operation must be of the same data type. Operations occur in the following order:

Parenthesis -- You can explicitly force the order of evaluation with parentheses. Operations within parentheses occur first. For example:
```
(5 - 3) * (6 - 4) = 4
```
Precedence -- Operations not in parentheses occur in order of precedence starting with precedence 1. For example, multiplication has greater precedence than subtraction so 3 * 6 occurs first:
```
5 - 3 * 6 - 4 = -17 
```
Left to right -- Operations of equal precedence occur left to right. For example:
```
8 / 4 * 2 = 4
```
