	'''Rounding''' can be challenging. Especially if the decimal you have to remove is a five, or the decimals you are up to remove are near ''498…'' or ''502…'', or - even worse - ''5001…''. Keep strong! There are simple rules for it. If not stated otherwise, we use commercial rounding (or ''rounding half away from zero'') in this wiki, trailing decimals 0,…,4 are rounded towards zero, 5,…,9 are rounded away from zero.

'''Rounding''' can be challenging. Especially if the decimal you have to remove is a five, or the decimals you are up to remove are near to ''498..'' or ''502..'', or - even worse - ''5001..''. Keep strong! There are simple rules for it. If not stated otherwise, we use commercial rounding (or ''rounding away from zero'') in this wiki, trailing decimals 0,..,4 are rounded towards zero, 5..9 are rounded away from zero.

Fourtunately, [[cent]] values of [[just interval]]s (except 1/1 and 2/1) are irrational.
