There are several ways to go about this.
One of the easiest ways is to use theMOD functionwith a divisor of 1.
INT or TRUNC
Another way to solve the problem is with theINT functionor theTRUNC function.
If the values match, we know we have a whole number.
Both formulas work fine, but note they behave differently with negative decimal values.
This matters for negative values, because they are rounded away from zero (i.e.
they become more negative).
That said, it doesn’t make a difference in this example.
For example, MOD(10,3) = 1.
The result of MOD carries the same sign as the divisor.
For example, TRUNC(4.9) will return 4, and TRUNC(-3.5) will return -3.
The TRUNC function does no rounding, it simply truncates as specified.
Note that negative numbers becomemore negative.
For example, while INT(10.8) returns 10, INT(-10.8) returns -11.
