Release:        20.04


ping is using the current locale to interpret the interval value: 

    ping -i 0.3 localhost

fails with "ping: bad timing interval: 0.3"
while this works:

    ping -i 0,3 localhost

This also works:
    LANG=en ping localhost -i .3

It seems similar to a 2015 bug from Fedora:
