Notice that for 2nd row, a digit after 2 places to the right of the decimal is less than five (5) however, the rounding digit is still increased by one with the result of 20.36 for number 20.35241.

Finally, on row 5, num_digit supplied ‘-3’ for the number ‘1232.82’ in cell A5 that instructs ‘ROUNDUP’ to round the number up to the next thousandths value, i.e. 2000.
