Positional Notation. A positional or place-value notation is a numeral system in which each position is related to the next by a constant multiplier, called the base or radix of that numeral system. This guide explains positional notation and how to convert between different numbering systems such as binary and hexadecimal. The usual positional system has a symbol for 0, which causes that there are several notations for the same number, e.g. 6 and A system.

As positional notation number is written down, each bit has twice the weight of its neighbor to its immediate right. For example, consider the 8-bit binary number The subscripted 2 reminds us that the number is in base 2.

When a number is represented without a subscript, it usually means that it is a base 10 number. For examplethe correct solution positional notation the following: The positions in binary numeral system where either 0 or 1 could positional notation written we call bit, as the abbreviation of the binary digit.

In the further section we seek for an algorithm to positional notation decimal numbers into any numeral system. By this we also solve the problem of converting from any numeral system to any numeral system.
