Shell: Robust way to remove trailing decimal point and zero in case there is a zero
In a bash script I have a (two digit) number with decimal point and one digit following.
In case there's a zero after the decimal separator, I want to trim the separator and the zero.
For
foo=26.5
..there should be no trimming. But in this case:
foo=26.0
My desired output would be:
foo=26
Is tr the right choice for it?
I tried it with the --delete .0 option but it simply deletes all of both character's appearences.
Thank you!

@ctac_: This probably only works forbashand removes everything after the dot. I suggest to replace*with0.

I think it's ok with all POSIX shell. It seems to me the OP don't tell all. Starting from 26.5, he want to get 26 ?
