TermCalc

termcalc (tc) is a simple Terminal Calculator.
It supports basic arithmetic operations and math functions.
Expressions can be entered in the terminal directly as arguments.

$ tc "4 + 3.5"

4 + 3.5 = 7.5

Without any arguments, it will start in interactive session.

Note that the snap will create a command named termcalc. It is recommanded
to create a tc alias like so:

$ echo "alias tc=termcalc" >> ~/.bash_aliases
