Combining it with my original solution the result would look like this: Code: C001 LBL C Maybe this version is a bit more prone to roundoff errors so that the last digit may be slightly off here and there: 1i1 => 0,99999999998, 0,999999999997 4i3 => 3,99999999999, 3,00000000001 0i3 => 1,4689...E11, 3 The last example assumes radians mode. OK, this may happen anytime as all we got are 12 digits instead of 15 the 35s uses internally. But on average the more complicated formulas in post #10 seem to exibit less of such problems. In all three cases it returns accurate results. Maybe because sine and cosine of the angle are avoided (only their sign is considered). Dieter
