Because rounding to the nearest whole number is equivalent to rounding down, rounding can be avoided by using an additional control variable that is initialized with the value 0.5. is added to this variable on every iteration. Then, if this variable exceeds 1.0, is incremented by 1 and the control variable is decremented by 1. This allows the algorithm to avoid rounding and only use integer operations. However, for short lines, this faster loop does not make up for the expensive division , which is still necessary at the beginning.
