Keying In Exponents
(enter exponent) is used whenever an exponent is part of a
number you are keying in. To use [EEX], first key in the mantissa,
then press and key in the exponent. For example, divide
95,600 by Avogadro’s number (6.0222 X 1026 kmol 1):

95600 [ENTER] 95.600.0000
6.0222 6.0222
EEX 6.0222 00 The 00 prompts you to key
in the exponent.
26 6.0222 26 (6.0222 % 10%)
(=] 1.6875 -22 kmol
To key in a number having a negative exponent of 10, first key in
the number and press [EEX], then press (change sign) to make
the exponent negative, and key in the exponent. For example, key
in Planck’s constant (6.6262 X 1034 Joule-seconds) and multiply it
by 50:

3 6.6262 -03
4 6.6262 -34
6.6262 -34
50 3.3131 -32 Joule-seconds.
Note: Decimal digits keyed into the exponent field will
disappear from the display when you press [EEX], but will be
retained internally.
