Javascript and Python handle the rounding of -x.5 differently. In JS, `Math.round(-0.5)` is equal to `-0`. In Python, `round(-0.5)` is equal to `-1`. This will lead to inconsistencies between Python and Javascript, but it can also lead to inconsistencies in the Javascript itself. Indeed, in the POS, a refund to the client is entered as a negative number. For example, `4.245` will be rounded to `4.25`, but a refund of `-4.245` will be rounded to `-4.24`. The payment and the refund are not consistent.
