In the terminal I always use “dc”, where, besides being RPN, you have to explicitly set the precision. I.e. the result of 2∕3 (or “2 3 /”) in dc is always ”0”

In the terminal I always use “dc”, where, besides being RPN, you have to explicitly set the precision. I.e. the result of 2∕3 (or “2 3 /”) in dc is always ”0” unless you set a precision beforehand. This makes it clear that the result is arbitrary.
