--Definiciones de funcion calculadora --Suma, resta, multiplicacion, division --Potencia, raiz cuadrada function add(x, y) res = x + y end function sub(x, y) res = x - y end function mult(x, y) res = x * y end function div(x, y) res = x / y end function pot(x, y) res = x ^ y end function rsqr(x) local r local t = 0 r = x while t ~= r do t = r r = (x/r + r)/2 end res = r end
And this is de main program:
os.loadAPI("calc")
local opc
print("Pick a number")
print("")
print("1. Add")
print("2. Subtract")
print("3. Multiply")
print("4. Divide")
print("5. Square of a number")
print("6. Root Square")
opc = io.read()
if opc == "1" then
print("First number:")
x = io.read()
print("Second number:")
y = io.read()
calc.suma(x, y)
print("")
print("Result: "..res)
x = nil
y = nil
elseif opc == "2" then
print("First number:")
x = io.read()
print("Second number:")
y = io.read()
calc.resta(x, y)
print("")
print("Result: "..res)
x = nil
y = nil
elseif opc == "3" then
print("First number:")
x = io.read()
print("Second number:")
y = io.read()
calc.mult(x, y)
print("")
print("Result: "..res)
x = nil
y = nil
elseif opc == "4" then
print("First number:")
x = io.read()
print("Second number:")
y = io.read()
calc.div(x, y)
print("")
print("Result: "..res)
x = nil
y = nil
elseif opc == "5" then
print("First number (base):")
x = io.read()
print("Second number:")
y = io.read()
calc.pot(x, y)
print("")
print("Result: "..res)
x = nil
y = nil
elseif opc == "6" then
print("Number:")
x = io.read()
calc.sqr(x)
print("")
print("Result: "..res)
x = nil
end
The problem is that the program don't add or deduct or nothing. It gives the same result always: "12". The "12" is because I had the functions in the api inside the main program without an api, and I was trying out the root square with 144.
Thanks =)
