Well, lets look at it this way ... tell me if this does anything for you:
-- Take the number 31.01 .
-- Stick a zero on the end and make it 31.010 .
-- Zeros at the end of a number after the decimal point don't change
the value of the number. So you haven't changed the value of 31.01 .
-- But now it looks exactly like the other number !
-- They must be equal.
