Conditional Format Last digit zero

[chesspupil]

Please help:

I am looking for a conditional format formula that looks at the last digit in the cell and asks if the digit is zero then the conditional format is true and I will direct excel to color the cell.
All vaules are numbers. Cells are currently set to round to nearest hundredth.

1.56 (false)
1.50 (true)
20.01 (false)
20.90 (true)
