The 1 may not actually be 1. Is it a number entered directly? Or the result of a formula? Try selecting the cell with 1 and format it to show more decimal places, you will most likely find that it is actually 0.96754 or something similar.Okay, how come when i apply ROUNDDOWN on 1.00 it appears to be 0?! supposed to be 1 right? can anyone help me here?
