Round a number off to n places.

number = round(number, decimals)

Function Parameters

Arguments

number

Number. The number to round.

decimals

Number. Round to this many places.

Returns

number

Number. The rounded number.

Example

local number = round(math.pi, 3)
print(number) -- prints 3.142

Code

function round(number, decimals)
    return (("%%.%df"):format(decimals)):format(number)
end

The above truncates after number of decimals. The below rounds (note the 0+ makes it remove trailing 0's)

function round(number,decimals)
    return 0+(("%%.%df"):format(decimals)):format(number+.1^(decimals+1)/2)
end
