Base-n Calculations

Use the [MODE] key to enter the BASE mode when you want to perform calculations using

Base n values. [MODE] [MODE] [3]

• 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 a 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.

• You can use the following logical operators between values in Base-n calculations: and

(logical product), or (logical sum), xor (exclusive or), xnor (exclusive nor), Not (bitwise

complement), and Neg (negation).

• You may not be able to convert a value from a number system whose calculation range

is greater than the calculation range of the resulting number system.

• The message “Math ERROR” indicates that the result has too many digits (overflow).
