CPM

Shows you the average amount of critical strikes you make per minute.

/CPM - displays the critical strikes per minute
/CPMreset - resets the count

This is my first addon, and I made it to get into Lua, don't be too harsh in those comments.

If you find any bugs, please leave a note in the comments. Thanks =)

Multiplying and dividing by the same number is what essentially does the "rounding". I really can't tell you why though.

The math.floor function rounds down to the nearest integer, so to round to the nearest hundredth using that particular function, you need to multiply by 100 so that the relevant decimal place is the one that the function acts on (units). The 0.5 gets added after the multiplication is done because of the order of operations, and therefore is effectively the same as adding 0.005 to the number before the multiplication. The result of that is that, since floor always rounds down, if the thousandths place is >=5, the resulting hundredths place will be increased by 1, otherwise it will stay the same.

In any case, using string.format is easier if the goal is to output text.

lua Code:

local originalnumber = 24.1258921
local newnumber = math.floor(.5+originalnumber*100)/100

And that's about it!
