Never used the TI SR-22? A very cool
"programmer's" desktop calculator.
7-segment Panaplex display. My department had one and kept it in the
machine room before the Programmer was introduced.
I have one. It does full floating-point arithmetic in all three bases
(8, 10, 16). With exponent in the same base. Watching it work, it's
pretty clear after a while that it converts to base 16, does the math,
and converts back. No logical operations (shifting and masking) to
speak of.
