HP Journal BCD calculator algorithms
FYI, past issues of the HP Journal include BCD calculator algorithm descriptions for square root (197705), trig functions (197706), inverse trig functions (197711), and logs (197804). Although not credited in the 197705 article, the square root algorithm is the same one used in the circa1955 Friden SRW10 mechanical calculator (with a link to its algorithm on that page).
