Javascript or Jquery rounding up to 1 decimal place

Question

I need to round up to 1 decimal place

If my number is 80.02 I need it to be 80.1.

tried

Math.ceil( (80.02).toFixed(1) ) but this rounds the number up to 81

How can I achieve this?

Answer 1

use Math.ceil( number * 10 ) / 10; for rounding off

for fixing it to one decimal place

(Math.ceil( number * 10 ) / 10).toFixed(1);

Answer 2

I think it should work perfectly:

parseFloat(13.2*13.23).toFixed(1)

output:174.6

for your 80.02 - 80.0 and for 80.06-80.1 which is good
