Elca (Extended Line Calculator) is a real-time calculator; that is, it evaluates expressions as you type them. It supports hexadecimal, octal, and binary numbers, complex numbers, variables, string, list and hash operations, etc. It can convert expressions from human style to valid Perl code before evaluating them, and has a mechanism for importing external modules, allowing almost arbitrary extensions. You can also specify expressions on command line; in this case, elca prints their results, one per line, and terminates.
