Binary, Pental, Octal, Decimal, and Hexadecimal Operations (N-base)

This calculator can perform conversions between numbers expressed in binary, pental, octal, decimal and hexadecimal systems. It can also perform the four basic arithmetic operations, calculations with parentheses and memory calculations using binary, pental, octal, decimal, and hexadecimal numbers. Furthermore, the calculator can carry out the logical operations AND, OR, NOT, NEG, XOR and XNOR on binary, pental, octal and hexadeci- mal numbers.

Conversion to each system is performed by the following keys:

@z: Converts to the binary system. ‘?’ appears.

@r: Converts to the pental system. ‘q’ appears.

@g: Converts to the octal system. ‘f’ appears.

@h: Converts to the hexadecimal system. ‘6’ appears.

@/: Converts to the decimal system. ‘?’, ‘q’, ‘f’ and ‘6’ disappear from the display.

Conversion is performed on the displayed value when these keys are pressed.

Note: Hexadecimal numbers A – F are entered into the calculator by pressing ,, m, A, 1, l, and ikey respectively.

In the binary, pental, octal, and hexadecimal systems, fractional parts cannot be entered. When a decimal number having a fractional part is converted into a binary, pental, octal, or hexadecimal number, the fractional part will be truncated. Likewise, when the result of a binary, pental, octal, or hexadecimal calculation includes a fractional part, the fractional part will be truncated. In the binary, pental, octal, and hexadecimal systems, negative numbers are displayed as a complement.
