11.1*9 = 99.89999999999999

Question

I am using javascript to calculate a basket total for a simple html5 application. But javascript giving me wrong result in mobile and pc side.

Tested in Safari and Chrome in Mac and Chrome in Android.

For example: 9.1*9= 81.89999999999999 11.1*9= 99.89999999999999

What can i do :D

What do you mean by "wrong result" ? Do you want values like 9.1*9 = 81.9 and 11.1*9=99.9 ? — Pavan Skipo, Dec 31 '18 at 07:18

Using Number.tofixed(n)

(9.1 * 9).toFixed(2) = "81.90"
