Module:Sandbox/IJReid/Mathematics explained

--Module to calculate basic math valuesmathematics =

mathematics.addition = function(input) --Addition function local sum = 0 --Define variable for use in loop for i, arg in pairs(input.args) do --Loop to run through all arguments sum = sum + arg --Add argument value to sum end return sum --Output the sum to the moduleend

mathematics.subtraction = function(input) --Subtraction function local dif = input.args[1] - input.args[2] --Subtract second argument from first return dif --Outpud difference to moduleend

mathematics.multiplication = function(input) --Multiplication function local product = 1 --Set product as 1 (so multiplication of it works) local pi = 3.141592653589793 --Set pi as 15 digits of precision for i, arg in pairs(input.args) do --Allow multiple arguments if (arg

"pi" or arg

"π" or arg

3.14) then --Set pi to π argument arg = pi else product = product * arg --Multiply arguments together end end return product --Output product to moduleend

mathematics.division = function(input) --Division function local quotient = input.args[1] / input.args[2] --Divide arg1 by arg2 return quotient --Output quotient to moduleend

return mathematics --Output module to place of use
