HP HP-67 User Manual

48 Display Control
The HP-67 also switches to scientific notation if the answer is too
large (=10°) for fixed point display. For example, the display will
not switch from fixed if you solve 1582000 X 1842:
Press Display
1582000 7582000.00
1842 2914044000. Fixed point format.
However, if you multiply the result by 10, the answer is too large
for fixed point notation, and the calculator display switches auto-
matically to scientific notation:
Press Display
10 E2 2.914044000 10| Scientific notation
format.
Notice that automatic switching is between fixed and scientific nota-
tion display modes only—engineering notation display must be
selected from the keyboard.
Keying In Exponents of Ten
You can key in numbers multiplied by powers of 10 by pressing [EZ4
(enter exponent of 10) followed by number keys to specify the
exponent of 10. For example, to key in 15.6 trillion (15.6 X 10'%),
and multiply it by 25:
Press Display
15.6
333 15.6 00
12 15.6 12| (This means 15.6 X
10'2)
Now Press Display
