DELTA
The DELTA function determines whether two values are exactly equal. This function
uses exact equality. By comparison, the = operator uses string-based equality.
DELTA(compare-from, compare-to)
 compare-from: A number. compare-from is a number value.
 compare-to: A number. compare-to is a number value.
Usage Notes
DELTA returns 1 (TRUE) if  compare-from is exactly equal to compare-to; otherwise
0 (FALSE) is returned.
Examples
=DELTA(5, 5) returns 1 (TRUE).
=DELTA(5, -5) returns 0 (FALSE).
=DELTA(5, 5.000) returns 1 (TRUE).
