# 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. |
