JavaScript - How To Detect Number As A Decimal (Including 1.0)

Question

It feels like I am missing something obvious here. This has been asked a number of times - and the answer usually boils down to:

var num = 4.5;
num % 1 === 0; /         


        

Answer 1

var num = 1;

and

var num = 1.0;

are the same. You mention that you want to treat them differently when given from a user. You will want to parse the difference when it is still a string and convert it to the appropriate number.
