# DIVIDEDAX Function (Math and Trig)

Safe Divide function with ability to handle divide by zero case.

## Syntax

DIVIDE ( <Numerator>, <Denominator> [, <AlternateResult>] )
Parameter Attributes Description
Numerator

Numerator.

Denominator

Denominator.

AlternateResult Optional

Optional. The alternate result to return when dividing by zero.

## Return values

Scalar A single decimal value.

Result of the division between Numerator and Denominator, or AlternateResult in case there is a division by zero.

## Remarks

Alternate result on divide by 0 must be a constant. By default, the AlternateResult argument is BLANK.
DIVIDE is faster than an IF statement checking whether the denominator is zero. However, DIVIDE is executed in the formula engine and it is not as fast as a native division.

## Examples

```--  DIVIDE performs safe division protecting from division by
--  zero. In case of zero denominator, it returns its third
--  argument that defaults to a blank.
DEFINE
MEASURE Sales[Unprotected Growth %] =
VAR CY = [Sales Amount]
VAR PY = CALCULATE ( [Sales Amount], SAMEPERIODLASTYEAR( 'Date'[Date] ) )
RETURN (CY - PY) / PY
MEASURE Sales[Protected Growth %] =
VAR CY = [Sales Amount]
VAR PY = CALCULATE ( [Sales Amount], SAMEPERIODLASTYEAR( 'Date'[Date] ) )
RETURN DIVIDE ( CY - PY, PY, BLANK () )
EVALUATE
SUMMARIZECOLUMNS (
'Date'[Calendar Year],
"Unprotected Growth %", [Unprotected Growth %],
"Protected Growth %",   [Protected Growth %]
)

```
Calendar Year Unprotected Growth % Protected Growth %
