Subject: Integer arithmetic vs double precision arithmetic
Date: Sun, 26 Mar 2006 20:44:36 +0530 [thread overview]
Message-ID: <200603262044.37068.samjnaa@gmail.com> (raw)
I am trying to work out whether to use an integer or a double for my internal
storage variable of a class meant to store a time.
Qt uses an unsigned integer with millisecond being the best precision, but I
am wondering, why I should lose the extra digits of precision that I could
get if I used a double.
Is there a marked increase in computing speed if integer arithmetic is used
compared to double precision?
