Subject: Re: In CVS Emacs, calc-eval gives multiplication higher precidence than division
Date: Tue, 09 Sep 2008 04:11:44 -0400 [thread overview]

There's no need to change the longstanding defaults, because it would break
things. You already have a knob you can tweak if you think that "2 a / 3 b"
should multiply by b, rather than divide by it. That's a personal choice.
Frankly, I'd never touch that knob, because it looks to me like it should
divide by b.
I agree completely -- in that case, it is natural for b to go in the
denominator.
The same is true for 1 / 2 * 1000: the meaning of 1/2000 is more
natural, mathematically.
What Calc does now is clearly correct.
