math.round()
Description:
Rounds number to the nearest integer following the same rules as the JavaScript version, i.e. if the fractional portion of number is .5 or greater, the argument is rounded to the next higher integer. If the fractional portion of number is less than .5, the argument is rounded to the next lower integer.
Syntax:
local value = math.round( num )
Example:
print( math.round( 0.1 ) ) -- Output: 0.1 0 print( math.round( 0.5 ) ) -- Output: 0.5 1 print( math.round( 8.9 ) ) -- Output: 8.9 9 print( math.round( -0.1 ) ) -- Output: -0.1 0 print( math.round( -0.5 ) ) -- Output: -0.5 0 print( math.round( -8.9 ) ) -- Output: -8.9 -9
Parameters:
num
Number to be rounded.
Returns:
number
Number rounded up or down.

- Mac OS X:Build 2011.514
- Windows:Build 2011.514

I don't think math.round is supported anymore. It gives me big greasy errors. I used math.floor instead.
