You may use fmod(result/1000.0)

you could use

n =  (int)(result/1000.0);
m = result - (n * (result/1000.0))

Open in new window


n and m should be float.

be aware that (int)(result/1000.0) is always 0 when abs(result) < 1000.

if result == .89 (as stated in the original post)  and you want .89 as the remainder you would do

remainder = result - (int)result;

Open in new window


if you want 890 for remainder (thousandth) simply multiply (not divide) the remainder by 1000.
