String functions

I've concluded that not all the string functions are in Lua. Am I right?

The following simply doesn't work

Code Select Expand

string.format("%.2f", num)

Confirmed. Oddly enough, using %s for floating-point numbers appears to work.

Thanks for the confirmation and the pointer to %s

I also guess using %s wouldn't allow you to control the decimal place formatting.

Not having %.xf is not an issue as I can achieve the result other ways. For instance in my DoF Bar I do this:

Code Select Expand

function myround(num,dp)
    -- num = a number, dp = decimal places required to show
    -- returns number as a string
    if dp == 0 then
        num = tostring(math.floor(num))
    else
        --text =
        num = tostring(math.floor(num)).."."..string.sub(tostring(math.floor(num*10^dp)),-dp,-1)
    end
    return num
end
