Hi,
I have the following Javascript code to make a simple calculation. It works fine the numbers entered are integer. But if the numbers are 1.5 style I get stupid results or NAN error.
I would like to add a check to the script which checks:
1- If the value entered is integer or 1.5 style for all fields. If it is not gives an alert message and stop calculating.
2- If the visitor enters 1,5 instead of 1.5 (In Turkey it is a common usage.) I need script replace the 1,5 with 1.5 and then make the calculation.
Thank you in advance

yuzdefaiz = faiz / 100;
ayliktaksit1 = ((kredimiktari * yuzdefaiz) + kredimiktari) / kredivadesi;
geriodeme1 = ((kredimiktari * yuzdefaiz) + kredimiktari);
document.getElementById(‘ayliktaksit’).innerHTML = “<strong>Taksit / Ay :</strong>” + ayliktaksit1;

The parseint functions seems to delete the part after the . but I don’t know how to fix the problem
