Engineering Notation Display
(ENG) fengineering) displays numbers in an engineering notation
format that operates the same as [SCI]notation format except:
e Engineering notation shows all exponents in multiples of
three.
e The number of digits specified for the display setting refers to
the number of significant digits you want to appear after the
leading digit.

Keying In Exponents
(EEX] (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 1076 kmol~!):

6.0222 00 The00 prompts you to key
in the exponent.
26 6.0222 26 (6.0222 x 1076)
ea] 1.5875 -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 10-4 Joule-seconds) and multiply it
by 50:

4 6.6262 -34
ENTER 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.
