Problems with Test
by James McKenzie 31 Oct '10

All: I'm trying to convert one integer number using a float number factor. Here is the code: int ry = 125; double ryf; ryf = ry/1440; The result is 0 and should be 0.06666666667 (or even more sixes.) BTW, if I change ry to 1440 the result is 1.00000. What am I doing 'incorrectly'? James McKenzie
