Odd and Even

[Ron Hudson <ron.hudson@...>]

I need to tell if a number is odd or even,
I have looked at "Programming in Lua" and
there does not seem to be a modulus
(remainder) operator, or and int functions
(returns the integer part of a floating
point numbner)

The only way I can think to do this
is to take the number, divide it by
2, turn it into a string and look
for the ".5"

Is there a better way?

Thanks
