Page 13: Entering Dimensions
Fixed Fractional Mode In the Fixed Mode (Ç 9), fractional results are displayed in the set fractional value, not reduced. Entries of higher accu- racy values will be rounded to the nearest Fraction of the accuracy setting (for exam- ple, for a Fraction level setting of 1/16, an entry of 5 / 3 2 = will result in a dis- play of 3/16). -
