Free42 is a complete re-implementation of the HP-42S calculator and the HP-82240 printer. Free42 was written from scratch, without using any HP code. You do not need any ROM images in order to use it, yet it is fully HP-42S compatible.
What's New in This Release:
· HMS+ and HMS- would return results with the wrong sign under certain circumstances: result < 0 and |result| < 59 seconds, or result < 0 and |result| > maximum integer. Fixed.
What's New in 1.4.70:
· Fixed several bugs in complex ASIN, ASINH, ACOS, and ACOSH.
What's New in 1.4.68:
· INVRT did not perform any type checks, leading to badness when it was applied to anything that wasn't a matrix. Fixed.
What's New in 1.4.66:
· Removed the "Not Yet Implemented" Time functions; I decided not to implement them. They're also gone from the FCN catalog. The ADATE, ATIME, ATIME24, CLK12, CLK24, DATE, DATE+, DDAYS, DMY, DOW, MDY, and TIME functions remain; those are the time/date-related functions from the HP-41 Time Module that are actually useful in Free42. The functions that I decided not to implement after all are the following: Live clock display: CLKT CLKTD CLOCK Stopwatch: RCLSW RUNSW SETSW STOPSW SW Alarms: ALMCAT ALMNOW XYZALM Clock control: CORRECT RCLAF SETAF SETDATE SETIME T+X
· In DMY mode, DATE would display dates as DD:MM:YYYY, but that should be DD.MM.YYYY. Fixed.
