Integer & Floating Conflict

What if, I'm not sure about the visitor input type in a form, where i have 2 variables to add together and return to our visitor . One input would be a integer and otherone floating. How should i handle this situation ?

I am not entirely sure the question, however I think you are asking if you can add a number and a floating number? The answer to that is yes:

var x = 1;
var y = 1.001;
console.log(x + y); // returns 2.001

You also might be asking about what if the input comes into the JavaScript as a string. You can parse a string into a number like so:

var x = "1";
var y = "1.001"; 
console.log(x + y); // returns "11.001"
console.log(parseInt(x, 10) + parseFloat(y, 10)); // returns 2.001

Or just use parseFloat to parse the input if you're not sure if it will be an integer or float, since it can handle integers no problem.
