Command-line based four-function RPN calculator, written for older DOS palmtops like the HP 95LX, but compiles and runs on Unix-like systems, too. Supports binary math and fraction math, as well as basic unit operations. Based on Freyja.
An upgrade of the program Moon 2.0 to revision 3.0. Several subroutines have been added, including the ability to calculate the moon phase now for any day/time (from 1582-10-15 to the future). It is also now multilingual.
This set of routines provides all of the operations (except division and percent) that are commonly found on adding machines. Instead of a paper printout, however, the list of numbers is stored electronically and can be reviewed and edited.
