Exponents Of Ten - HP -32S Owner's Manual

Exponents off Ten
Exponents in the Display. Numbers with exponents of ten (such as
4.2 x 10~5) are shown in the display with an E preceding the expo
nent (such as 4.2080E-5). A number whose magnitude is too large
or too small for the display format will automatically be displayed in
exponential form. For example, in FIX 4 format for four decimal
places, observe the effect of the following keystrokes:
Keys:
.000062
I ENTER I
.000042 I ENTER
Display: Description:
8.000062. Shows number being
entered.
0.0001 Rounds number to fit
display format.
4.2000E-5 Automatically uses sci
entific notation
because otherwise no
significant digits would
appear.
Keying In Exponents of Ten. Use (T) (exponent) to key in numbers
multiplied by powers of ten. For example, take Planck's constant,
6.6262 xlO"34.
1. Key in the mantissa (the non-exponent part) of the number. If
this part is negative, press F£).
6.6262 6.6262.
2. Press (T). Notice that the cursor moves behind the E.
[§0 6.6262E.
3. Key in the exponent. (Largest possible exponent is ±499.) If it is
negative, press Pip.
34 TO 6.6262E-34.
For a power of ten without a multiplier, such as 1034, just press (T) 34.
The calculator displays IE34.
