So rounding is done there. It has to be rounded, as you are never paid a fraction of a penny. This infinitely repeating decimal is unhandy. We rounded the third decimal place. But, for many practical purposes, the equal sign is fine, especially since I do not have an approximately equal sign available to me.
Computers often truncate.
It is easier than rounding. Bowling averages are truncated. That is the law. Consider a person who is supposed to round 3.5. There is rampant confusion here.
