floating point number?

floating point number?

Hi, one of the steps for this challenge is to convert the string from the users input to a floating point number. Why a floating point number and not an integer? thanks.

Hello Modestats,
First of, I'm sorry if I don't understand your question precisely.
I think you're asking why it has to be parseFloat instead of parseInt. If it is, it's because you have decimal numbers after the first (example: 15.57 is a decimal number 15 is not) then you have to use parseFloat

So what I mean is:
parseInt is used to none decimal numbers (fx: 1, 7, 10000 or 28345)
parseFloat is used to decimal numbers (fx: 1,5 3,14 634,23 38,32435)

exsample in code:

var number1 = "10";
var number2 = "10.5";
parseInt.number1;
parseFloat.number2;
console.log(number1, number2);

I hope this helped, have a nice day and happy coding! :)
