• You cannot use scientific functions in binary, octal, deci-
mal, and hexadecimal calculations. You cannot input val-
ues that include decimal part and an exponent.
• If you input a value that includes a decimal part, the unit
automatically cuts off the decimal par t.
• Negative binary, octal, and hexadecimal values are pro-
duced by taking the two's complement.
• You can use the following logical operators between
values in Base- n calculations: and (logical product), or
(logical sum), xor (exclusive logical sum), xnor (exclu-
sive logical sum negation), Not (negation), and Neg (mi-
nus).
• The following are the allowable ranges for each of the
available number systems.
