# NEGATE Function

Returns the opposite of the value that is the first argument. Equivalent to the - operator placed in front of the argument.

• The argument can be a literal Integer or Decimal number, a function returning a number, or a reference to a column containing numeric values.

Nota

Within an expression, you might choose to use the corresponding operator, instead of this function. For more information, see Numeric Operators.

Wrangle vs. SQL: This function is part of Wrangle, a proprietary data transformation language. Wrangle is not SQL. For more information, see Wrangle Language.

## Basic Usage

negate(MyValue)

Output: Returns the opposite of the value in the MyValue column.

### Example - Numeric Functions

This example demonstrates how to use numeric functions to perform computations in your recipe steps.

Functions:

Item

Description

ADD Function

Returns the value of summing the first argument and the second argument. Equivalent to the + operator.

MOD Function

Returns the modulo value, which is the remainder of dividing the first argument by the second argument. Equivalent to the % operator.

NEGATE Function

Returns the opposite of the value that is the first argument. Equivalent to the - operator placed in front of the argument.

SUBTRACT Function

Returns the value of subtracting the second argument from the first argument. Equivalent to the - operator.

MULTIPLY Function

Returns the value of multiplying the first argument by the second argument. Equivalent to the * operator.

DIVIDE Function

Returns the value of dividing the first argument by the second argument. Equivalent to the / operator.

LCM Function

Returns the least common multiple shared by the first and second arguments.
