Re: floor()
--=====================_113246286==_.ALT
Atoms are approximations of decimal numbers a decimal number, say .1, might
actually be stored as .0999999999999
10 * .0999999999999 = .999999999999 which is <1 and therefore floor would
report the value as 0
We just have a long thread about this. If you want to make sure floor works add
.00001 or so to the number you are using floor on and see if the results become
more consistant
