• 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.
