# DELTA Function

The DELTA function is one of the engineering functions. It is used to test if two numbers are equal. The function returns 1 if the numbers are equal and 0 otherwise.

The DELTA function syntax is:

DELTA(number-1 [, number-2])

where

number-1 is the first number.

number-2 is the second number. It is an optional argument. If it is omitted, the function will assume number-2 to be 0.

The numeric values can be entered manually or included into the cell you make reference to.
