DELTA function

This article describes the formula syntax and usage of the DELTAfunction in Microsoft Excel.

Description

Tests whether two values are equal. Returns 1 if number1 = number2; returns 0 otherwise. Use this function to filter a set of values. For example, by summing several DELTA functions you calculate the count of equal pairs. This function is also known as the Kronecker Delta function.

Syntax

DELTA(number1, [number2])

The DELTA function syntax has the following arguments:

  • Number1    Required. The first number.

  • Number2    Optional. The second number. If omitted, number2 is assumed to be zero.

Remarks

  • If number1 is nonnumeric, DELTA returns the #VALUE! error value.

  • If number2 is nonnumeric, DELTA returns the #VALUE! error value.
