2.5.1 – Arithmetic Operators

Lua supports the usual arithmetic operators: the binary + (addition), - (subtraction), * (multiplication), / (division), % (modulo), and ^ (exponentiation); and unary - (negation). If the operands are numbers, or strings that can be converted to numbers (see §2.2.1), then all operations have the usual meaning. Exponentiation works for any exponent. For instance, x^(-0.5) computes the inverse of the square root of x. Modulo is defined as

a % b == a - math.floor(a/b)*b

That is, it is the remainder of a division that rounds the quotient towards minus infinity.

I want allow only 2 numbers after comma if is more than 2 numbers then show error or format to number with 2 numbers after comma

[Noki]

math.round(5.924613, 2) 

> 5.92

The second argument is the number of decimal places.

math.round(5.924613, 2) 

> 5.92

The second argument is the number of decimal places.

This function doesnt works

Because it's not a build-in function. You must add it by yourself. See here - https://wiki.multitheftauto.com/wiki/Math.round.

This migth be useful I use it for all of my number formatting,

function comma_value(amount) 
  local formatted = amount 
  while true do   
    formatted, k = string.gsub(formatted, "^(-?%d+)(%d%d%d)", '%1,%2') 
    if (k==0) then 
      break 
    end 
  end 
  return formatted 
end 

Example of usage:

outputChatBox("You have recieved: $" ..comma_value(amount).. " into your bank account",source,0,255,255)
