Does the 'bc' calculator function not work here on repl?

A beginner bash coder here. Was trying out arithmetic operation on decimal numbers with ' | bc ' command option. This results in an error, saying bc command not found. What is the way out?

You can't have decimals in bash, but you can sue some trickery:

echo $(( 100 * 1 / 3 )) | sed 's/..$/.&/'

Check this SO question for more information. Hope it helps :)

install-pkg bc dc.

I like dc, but it's postfix notation.
