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? -- Tux #395953 resides at http://samvit.org playing with KDE 3.51 on SUSE Linux 10.0 $ date [] CCE +2006-03-26 W12-7 UTC+0530 - : send the line "unsubscribe linux-c-programming" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
