Converting Numbers

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.
binary, octal, decimal, and hexadecimal number systems.
