Lua DOES have a 'round' function - 2 in fact .... math.floor() rounds 
down for you, and math.ceil() rounds up for you. :)

If that's not what you want, you can write one to do what you want in a 
few seconds. Making a 'math.round' which rounds to the nearest integer 
is a couple of lines of code. You can always just add that to your 
standard set of functions you use. If you can't do write a 'math.round' 
function, then you probably couldn't use Lua much at all anyway.

Lua is minimalist. math.round() can trivially be added to do what you 
want using the existing functions. The maths library is generally just 
stuff which is harder to do - eg making a math.floor() would actually be 
quite hard, as would math.cos, math.log etc.
