# Operators

The workflow programming language supports several standard Java operations. These operations are special symbols that performing specific operations on one or more operands and return a result.

Operators by Type

## Unary

A unary operation is an operation with only one operand.

Operator

Description

`++`

Increases the value of an operand by 1.

`--`

Decreases the value of an operand by 1.

`!`

Logical NOT.

## Relational

A relational operator compares the relationship between two entities. Returns a `Boolean` value that states whether the comparison is true or false.

Operator

Description

`<`

Less than operator.

`>`

Greater than operator.

`<=`

Less than or equal operator.

`=>`

Greater than or equal operator.

## Equality

Evaluates the equivalence of two operators. Returns a `Boolean` value that states whether the equivalence is true or false.

Operator

Description

`==`

Equality operator.

`!=`

Inequality operator.

## Assignment

Assigns a value to its left operand based on the value of its right operand.

Operator

Description

`=`

Assigns a value to a variable.

## Binary Logical

Logical operators are typically used with Boolean (logical) values. Return a Boolean value.

Operator

Description

`&&`

Logical AND.

`||`

Logical OR.

## Arithmetic

Arithmetic operators take numeric values (either literals or variables) as their operands and return a single numerical value.

Operator

Description

`+`

Addition operator. Concatenates string types, adds integers, summarizes dates and time-related values.

`-`

Subtraction operator.

`*`

Multiplication operator.

`/`

Division operator.

`%`

Remainder operator.

The `+` and `-` operators can also be used with dates, periods, and durations. For more information, see Working with Dates and Times.

## Grouping

The grouping operator consists of a pair of parentheses around an expression or sub-expression.

Operator

Description

`( )`

Overrides the normal operator precedence so that expressions with lower precedence can be evaluated before an expression with higher priority.
