In addition to decimal values, calculations can be
performed using binary, octal and hexadecimal values.
•You can specify the default number system to be applied
to all input and displayed values, and the number system
for individual values as you input them.
•You cannot use scientific functions in binary, octal,
decimal, and hexadecimal calculations. You cannot input
values that include decimal part and an exponent.
If you input a value that includes a decimal part, the unit
automatically cuts off the decimal part.
•Negative binary, octal, and hexadecimal values are
produced by taking the two’s complement.
