I am looking to make a decimal number return to zero. Example

if AI EQUALS 37.5

I want to do a formula that divides AI by 2 and when it comes out to 18.75
which is not a whole number then it should state the cell as zero if it is
a whole number then it would return the whole number to that cell.

Maybe something like this:
=IF((A1/2) = INT(A1/2), A1/2, 0)
