1. abs() , rnd() func or integer cast?
Hi everyone, maybe I just missed it, but i can't find a lib function
or builtin to isolate the integer part of a number. I need to just take
the integer part of a division result, but amazingly I can't find any way
of doing this in Euphoria. I searched the docs for either a integer divide
such as DIV in pascal, or a lib function strip the decimal part off a number
so I can use it as an indice in a sequence!

1/ Check the manual for floor(), you'll be delighted.
2/ Sequence indexes are rounded down to integers if non integer atoms, so you
don't even need to call floor() in this case, the interpreter does it for you.
