• Negative numbers in binary, octal and hexadecimal are

expressed as two's complements.

• To distinguish the A, B, C, D, E and F used in the

hexadecimal system from standard letters, they appear
as shown in the chart below.

Binary Positive : 1111111111

Negative : 1111111111

1000000000

Octal

Positive : 777777777

Negative: 7777777777

4000000000

Decimal 2147483647

-2147483648

Hexadecimal Positive : 7FFFFFF

Negative: FFFFFFFF

80000000

• You cannot specify the unit of angular measurement

(degrees, radians, grads) or the display format (Fix,
Sci) while the calculator is in the BASE-N mode. Such
specifications can only be made if you first exit the
BASE-N mode.
