Reminder is returned as float while using javascript function

**vishnu** ([Bug 65450](https://bz.apache.org/bugzilla//show_bug.cgi?id=65450&redirect=false)):
Finding reminder using the __javascript function returns a float when expected an integer. This happens only when the reminder is 0
ex: _javascript(20%2) gives output as '0.0'

This was not there in the previous versions.
as a workaround we can use the toFixed(0) function.

Severity: minor
OS: All

Start by reproducing the JavaScript function case described in the issue, using _javascript(20%2), and inspect the implementation responsible for evaluating that function. Done means the zero remainder is returned as an integer rather than 0.0, with a regression test covering the reported case.
