Challenge of the Month - July 2016 RRS feed

  • General discussion

  • These challenges are intended for people who are learning to program for the first time or for those returning to programming who want to start using Small Basic.  Some will be easy, some will be hard - but they will all make you think, and more importantly be GREAT FUN!

    Please post your solutions / partial solutions / questions / feedback etc. into this thread that will remain 'sticky' for the month.  The only rule is that your solution must use standard Small Basic methods (no extensions).

    It would be good if people could post their problems with these challenges so that a discussion can start so that everyone can learn from each other.

    We may extend these challenges over into a second month if solutions and questions are still coming in.

  • This is my second step for July Challenge : Auto loan Calculator

    this version compute bi-monthly payment , when you enter (y) in the box.

    the results has been verified with this website:  http://www.financeformulas.net/Loan_Payment_Formula.html

    so exemple: Borrow to buy a car : 15999$ at 0,99% interest rate per year for 5 years , in bi-monthly payment, so 130 payment it gives this:

    bi-monthly payment: 126,16$

    program no: RLL741

    nice Calculator, very useful, beautiful design !

    The next step would be to try to make a basic financial calculator, that would compute loan payment , simple interest deposit, compound interest :)

    here is what i want to do, i took your program ZNG033 and add keys Pv , n , i , P

    to compute a car loan payment . What do you think ? whats is missing, what can i add to the program ?

    program no: PQV320

    try it, here is the procedure to compute a car payment with this calculator:

    start:
    enter 12590.36
    press Pv
    enter 60
    press n
    enter 9.2
    press i
    press P
    press GT
    IT GIVES: monthly payment for $12590,36 for 60 months at 9.2% interest rate
    P= 262.57$
