--Module to calculate basic math values
mathematics = {}
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 module
end
mathematics.subtraction = function(input) --Subtraction function
local dif = input.args[1] - input.args[2] --Subtract second argument from first
return dif --Outpud difference to module
end
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 module
end
mathematics.division = function(input) --Division function
local quotient = input.args[1] / input.args[2] --Divide arg1 by arg2
return quotient --Output quotient to module
end
return mathematics --Output module to place of use
