This JavaScrpit function produce Correct Result

But Same logic not working in C#

void MyFunction()

{

double amount =Convert .ToDouble ( textBox1.Text) ;

double months =Convert .ToDouble ( textBox2.Text) ;

double intrest =Convert .ToDouble ( textBox3.Text) ;

double quaters = Math.Floor (months / 3);

double maturityamt = int.Parse (textBox1.Text ) * ((Math.Pow (intrest / 400 + 1, quaters) - 1) / (1 - (Math.Pow (intrest / 400 + 1, (-1 / 3)))));

textBox4.Text = maturityamt.ToString ();

}

for amount = 100, duration 12, intrest = 12.5
for complete formula
Java Script Function's output is 1283.54

Find below analysis:

(Math.Pow(intrest / 400 + 1, (-1 / 3))) -> 1
(1 - (Math.Pow(intrest / 400 + 1, (-1 / 3)))) -> 0
(Math.Pow(intrest / 400 + 1, quaters) - 1) -> 0.13098
((Math.Pow(intrest / 400 + 1, quaters) - 1) / (1 - (Math.Pow(intrest / 400 + 1, (-1 / 3))))) -> infinity

Because, 1/0 = infinity

Please check what you are getting above values in Javascript.

Plz help,

But Same logic not working in C#

void MyFunction()
{
double amount =Convert .ToDouble ( textBox1.Text) ;
double months =Convert .ToDouble ( textBox2.Text) ;
double intrest =Convert .ToDouble ( textBox3.Text) ;
double quaters = Math.Floor (months / 3);
double maturityamt = int.Parse (textBox1.Text ) * ((Math.Pow (intrest / 400 + 1, quaters) - 1) / (1 - (Math.Pow (intrest / 400 + 1, (-1 / 3)))));

Messege.Show( maturityamt);
}

Java Script function output = 1283.54

while c# function output = 'infinite'

Try With This

amount = parseFloat(document.getElementById("Amount").value);
months = parseInt(document.getElementById("Months").value);
intrest = parseFloat(document.getElementById("Intrest").value);
quaters = Math.floor(months / 3);
monthpayment = parseInt(amount) * ((Math.pow(intrest / 400 + 1, quaters) - 1) / (1-(Math.pow(intrest / 400 + 1,(-1/3)))));
document.getElementById("MaturityAmt").value = monthpayment.toFixed(2);
+1
