5-1 Before Beginning a Binary, Octal, Decimal, or
Hexadecimal Calculation
You can use the RUN Mode and binary, octal, decimal, and hexadecimal settings to
perform calculations that involve binary, octal, decimal and hexadecimal values. You
can also convert between number systems and perform logical operations.
• You cannot use scientific functions in binary, octal, decimal, and hexadecimal
calculations.
• You can use only integers in binary, octal, decimal, and hexadecimal calcula-
tions, so fractional values are not allowed. If you input a value that includes a
decimal part, the unit automatically cuts off the decimal part.
• If you attempt to enter a value that is invalid in the number system (binary, octal,
decimal, hexadecimal) you are using, the calculator displays an error message.
The following shows the numerals that can be used in each number system.
Binary: 0, 1
Octal: 0, 1, 2, 3, 4, 5, 6, 7
Decimal: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
Hexadecimal: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F
• The alphabetic characters used in the hexadecimal number appear differently on
the display to distinguish them from text characters.
Normal Text: A, B, C, D, E, F
Hexadecimal Values: u, v, w, x, y, z
• Negative binary, octal, and hexadecimal values are produced using the two’s
complement of the original value.
• The following are the display capacities for each of the number systems.
Number System Display Capacity
Binary 16 digits
Octal 11 digits
Decimal 10 digits
Hexadecimal 8 digits
• The following are the calculation ranges for each of the number systems.
Binary Values
Positive: 0 <
x < 111111111111111
Negative: 1000000000000000 < x < 1111111111111111
