3. Binary, Octal, and Hexadecimal Calculations
In addition to the normally used numerical expression of decimals, binary, octal, and
hexadecimal numerical expressions may be used.
This calculator allows conversions and calculations using the four rules of arithmetic
and boolean operations of numerical values expressed in decimals, binary, octals,
and hexadecimals
(1) Binary, octal, decimal and hexadecimal numbers
Decimal (DEC): Most commonly used expression of numerical values using
numbers from 0 to 9.
Binary (BIN): Expression of numerical values using only 0 and 1.
Octal (OCT): Expression of numerical values using numbers from 0 to 7.
Hexadecimal (HEX): Expression of numerical values using numbers from 0 to 9 and
letters A, B, C, D, E, and F. A to F represent numbers 10 to 15
and letters A, B, C, D, E and F are used in this calculator. Use
