Overflow And Underflow Displays - HP -01 Owner's Manual

The two-digit exponent of 10, displayed on the right, will be positive if you are dealing with large
numbers and will be negative if you are using very small numbers.
.0000000625 = 6.25 x 108
(Move the decimal point 8 places to the
left.)
(Move the decimal point 7 places to the
right.)
62500000 = 6.25 X 107 B.25
As you can see from these two examples, scientific notation is nothing more than a mathe-
matical "shorthand." Your HP-01 display automatically returns to decimal notation when the
number or answer falls within the seven-digit display range again.
OVERFLOW AND UNDERFLOW DISPLAYS. If an answer is greater than 9.999 x 10°%,
the display will show §.999 99 and will flash on and off.
If you calculate an answer smaller than 107°%, zero is displayed. (The display will not flash since
1 X 107%° is very close to zero.)
