How to make $((5/2)) giving me 2.5 ?

your $PS1 is quite funny. any way you need to use another shell like ksh93, yash or zsh, or use another tool for the maths — phuclv, May 20 '17 at 11:08
@LưuVĩnhPhúc it is unicode, so any shell supporting unicode will work. That is all of them, though some struggle with non-ascii, when calculating widths. However you may need to install a new font, maybe a different terminal emulator. — ctrl-alt-delor, May 20 '17 at 13:21

You can't. Bash will only work with integers. For more precision, use something like bc.
