Javascript parseFloat issue

Question

I am facing a new problem. I have the below use case.

var a = parseFloat(10); // Returns 10
var b = parseFloat(1.62); // Returns 1.62
var c = a + b; // Returns 11.620000000000001

I want the c to return 11.62. What is the problem here?

Answer 1

var a = parseFloat(10); // Returns 10
var b = parseFloat(1.62); // Returns 1.62
var c = a + b; // Returns 11.620000000000001

console.log(c.toFixed(2))    
Output: 11.62

console.log(c.toPrecision(4))
Output: 11.62

Answer 2

var a = parseFloat(10); // Returns 10
var b = parseFloat(1.62); // Returns 1.62
var c = a + b; // Returns 11.620000000000001
console.log(c.toPrecision(4));

Output: 11.62
