Reply #1 - Oct 25th, 2008, 6:07pm   Maybe this? float truncate(float x){  if ( x > 0 )    return float(floor(x * 100))/100;  else    return float(ceil(x * 100))/100; } Shifts the decimal point two spots to the right, floors (or ceils) it, effectively cutting off the post-decimal digits, shifts back.
