L' Eomot Inversé (7/1/2013)

. . . The very earliest floating point hardware implementation (Zuse, 1941) was neither electronic nor part of a stored program computer and had much smaller precision (15 bits - so nominally decimal precision 3) and hence wasn't useful for any complex calculations unless a great lack of accuracy was acceptable.

Z1 was built in 1936.

I should have said "commercial hardware implementation" instead of just "hardware implementation" . . .
