Restrict decimal error - conditional

Hello I have made a measurement, which calculates the difference between the two columns, giving a column difference, the three columns have two-digit currency format, but when you put the conditional formatting, it does not do it correctly when taking more decimals than I use(2)

I want that when it is zero to two decimal places, the marked option is applied.

If I put more decimals, it would indeed be correct, but I am only interested in working with two decimal places.

Any ideas?
