Hi,
I need to truncate values in a For loop and round() isn't working. I was just wondering why there is no truncate function yet?

Because round sometimes rounds up - away from zero. I think you may want to use fix() instead of round(). It always rounds towards zero, in other words, truncates. See if that works for you and let me know.

You should also know about floor(), which rounds towards negative infinity -- the maximum integer less than or equal to the input.

Thanks for your help, fix() works. Can do x=x-rem(x,0.001) as well.
