Excel PMT function in JS

Question

I found i little snipet on internet, about PMT calculate.

function PMT(i, n, p) {
 return i * p * Math.pow((1 + i), n) / (1 - Math.pow((1 + i), n));
}
function C         


        

Answer 1

Try it like this:-

function CalculatePMTFromForm(idLoanAmount, idAnnualInterestRate, idMonths, idResult) {
 var i = parseFloat($('#' + idAnnualInterestRate).val()) / 1200;
 var n = parseFloat($('#' + idMonths).val());
 var p = parseFloat($('#' + idLoanAmount).val());
 var pmt = PMT(i, n, -p);
 $('#' + idResult).val(pmt.toFixed(2));
}

The .val() is likely returning a string type not a number type.
