Converting Numbers Overview of Numbering Systems

Overview of Numbering Systems

Internally, a computer stores data as a series of off and on values represented symbolically by the binary digits, or bits, 0 and 1, respectively. Because numbers represented as strings of binary 0s and 1s are difficult to read, binary numbers are generally converted into octal, decimal, or hexadecimal form. Table D-1 describes the binary, octal, decimal, and hexadecimal number systems.

In manuals for the NonStop server, a percent sign precedes a number that is not in decimal form:

The % notation precedes an octal number.

The %B notation precedes a binary number.

The %H notation precedes a hexadecimal number. On some system displays, hexadecimal numbers are preceded by the notation 0X instead of %H.
