Hi,

I am new using corona SDK, and I want to round a number with 2 digits after the dot.

Like this: 5.44444 -> 5.44 , and 10.113 -> 10.11 

I found only this function (math.round) that round all my number

Thank you in advance  :slight_smile:

-- == -- round(val, n) - Rounds a number to the nearest decimal places. (http://lua-users.org/wiki/FormattingNumbers) -- val - The value to round. -- n - Number of decimal places to round to. -- == local function round(val, n) if (n) then return math.floor( (val \* 10^n) + 0.5) / (10^n) else return math.floor(val+0.5) end end

print( round( 1.5678 ) ) – prints: 1.57
