this.props.credit = '4.10';
 let rate = this.props.credit*100;

I used all parseFloat and Number types along with credit. But the result is always getting as 409.99999999999994. But we know actually the value is 410. Why is getting point difference in reactjs

This is how javascript behaves and yes it is sometimes quite strange.
