Lua division issue

[Blueman]

I was thinking before writing a code and I found a Issue it appears.

If I wrote a code to divide a players money by 40 it would return a decimal in some cases and I need it to be a whole number.

Is there any way to convert a decimal to a whole number in lua.

tonumber 

maybe?

[Blueman]

I'll try that, and thanks.

Edit: How exactly do you use tonenumber Google and the Lua guide offer little.

tonumber(text)

roundednum=math.floor(number*(10^digitCountAfterDot)+0.5)/(10^digitCountAfterDot)

Or just use this function

function math.round(number, decimals, method) 
    decimals = decimals or 0 
    local factor = 10 ^ decimals 
    if (method == "ceil" or method == "floor") then return math[method](number * factor) / factor 
    else return tonumber(("%."..decimals.."f"):format(number)) end 
end 
  
--now use it on any number like this 
math.round(number)

Or, you could use:

  
math.floor(float) --Rounds DOWN to the nearest whole number 
--or 
math.ceil(float) --Rounds UP to the nearest whole number 
  

Same as what JR10 posted but a little simpler, just depends on whether you want to be a little generous or a little stingy.

[JR10]

Well, why when you got a function that will just make it integer math.round is better.

Not necessarily - your function has 3 arguments, and in the end the scripter is going to have to choose between "ceil" or "floor", the only thing that is slightly more convenient is the decimal option, but for his case he just needs to round to a whole number.

Wow I go to bed and wake up with more responses then I estimated I would have and thanks you all helped.

No, the 2 last arguments are optional incase you want to use it ciel or floor leave em blank to use round method.

You can simply use this to round to the nearest number (note a string is returned, so use tonumber if needed);

string.format("%.0f",numberVariable)
