Hey everyone. First post so sorry if this is in the wrong place. I'm doing research the field for school so I don't have time to do proper forum analysis. I'm researching radio signals, and need help finding out how to make a custom formula. Right now I am using multiple sheets and rounding equations to log my research for one frequency band. The problem it's, is that I'm now using multiple frequency bands so this won't work. I need to be able to write an equation that will say: if the number is between a and b, rind it to the nearest hundredth. If it's between b and c, round it to the nearest even number in the tenth column. And so on. Different frequency bands have different channel spacing, so that's why I need the equation to identify which band it's in and round it accordingly. Any help would be great.thanx!!
