Wow, this sounded so weird i decided to check it myself... and got the same results :/ I think i'm gonna dig through all my code to see if i'm not doing the same thing. *sigh* stupid base 2 computers Michiel Sofie Van Landeghem wrote:

for (double cutoff = 0.0; cutoff <= 1.0; cutoff += 0.05)
results in these values for "cutoff":
0.0 0.05 0.1 0.15000000000000002 0.2 0.25 0.3 0.35 0.39999999999999997 0.44999999999999996
etc.
Not ending with 1.0, as you'd hope, but with 0.9500000000000003
(right, I know, take an int as loop variable and calculate the double inside the loop, but still ;-))
