Hmm in a CompSci course I'm taking they just move it from a double to an int to cause 'truncation'. Course 4.5 would end up being 4 even, and 4.999999 would be 4 even too.. Truncation and rounding are two totally different commodities. But that's just my two-cents :) At 12:52 PM 10/21/98 -0500, EddieB wrote: > >> >> > rintf(3.5) returns 4.0 >> > rintf(3910.5) returns 3910.0 (should return 3911.0) >> > >I haven't really the slightest clue about coding (Yea I'll admit it) but I >do remember from physics / chemistry classes that .5 #'s are rounded >different.
