Perleval is a little Perl script that works as a terminal-mode calculator. It can evaluate any Perl expression and can handle normal real arithmetic, complex arithmetic, and rational arithmetic. It also displays all integer results in decimal, hexadecimal and binary, making it very useful for computer programmers.

Perleval depends on a number of Perl modules, namely:
Perleval is a Perl script (naturally). Installation looks like this:
tar xf perleval-1.0.tar.gz && cd perleval-1.0 && perl Makefile.PL && make && sudo make install

To run Perleval, open a terminal window and enter: perleval
At the perl> prompt, enter an expression to evaluate. Enter help for a brief help page.
