Calculating interest / Help with functions

[Skilgannon]

I don't quite understand how functions work, and that's probably why this isn't working so well.
Basically, you input the original amount of money, the interest rate and the number of years , and it's compounded yearly.
For some odd reason, it only outputs the first number following "result"
Can someone help me out ?

code:

function invest (p, i, n : int) : int     result p*(1 + i div 100)**n end invest var p1, i1, n1 : int := 0 put "Enter amount of money invested" get p1 put "Enter interest rate, in percentage" get i1 put "Enter number of years" get n1 put invest ( p1, i1, n1)

I don't know why it would be outputing "result" but I do know that money is not an integer value. You should be using floating point varaibles instead of integers.

Thanks, I figured it out.

I'm not actually a turing user, so I don't know exactly what the type would be, but try "float", "double" or "real". Basically it's a variable that can keep track of decimal numbers.

Oh I wish Turing had floats and doubles...would be so much more memory effcient! I believe it does have some other random things with regards to natural numbers...

Turing doesn't support floats or doubles?!

/me shakes his head and walks away

Turing calls this type real.

var n : real
