Thank you guys! you gave me valuable insights! But regarding my original post, I don't know why for the past two days I was looking at the code *only* this way>
if ( not allow_zero and abs(x) ) < sys.float_info.epsilon:
I feel so stupid now :-/, may be it's the new syntax confusing me :)! Thanks again guys.
