I would fight for the current calc implementation, it is an important convenience when entering equations. I am relying on it every day.

Given the original author's mathematics bias, it made sense (to me, as an early tester and contributor) that: 2 * 3 / 4 * 5 would be parsed as (2 * 3) / (4 * 5) in a mathematical sense.Admittedly, if you're a computer-science guy and not a math guy, this mightseem initially odd. --Randal L.
