Display formats
Even though the calculator has a display and entry limit of ten digits, the
internal display register holds calculated results to 13 digits for greater
accuracy in following calculations The value displayed Is rounded to ton
digits.
In addition to the standard ten digit floating decimal display, there are
several other display formats available to Increase the versatility of the
calculator
EE! — Scientific Notation Key
Many scientific and engineering calculations involve very large or small
numbers which can be awkward to manipulate Scientific notation makes
these values easier to handle Any number can be expressed in scientific
notation as a base value (mantissa) limes 10 raised to some power
(exponent). For example, the value 1.050.000 is expressed as 1 05 x ICr In
scientific notation. The sign (+ or -) of the exponent indicates where the
decimal point is placed when the number is written in standard form A
positive exponent indicates that the decimal is shifted to the right to display
the number in standard format, and a negative exponent indicates that it Is
shifted to the left The value of the exponent gives the number of places the
decimal point Is to be moved The following (able shows some numbers
expressed in both slandard form and scientific notation.

± 1 x 10'9 and larger than ± 9 999999999 x 10* must be enlered into the
calculator in scientific notation If calculations exceed these limits, the
results are automatically displayed in scientific notation
