Non-standard positional numeral systems here designates numeral systems that may loosely be described as positional systems, but that do not entirely comply with the following description of standard positional systems:

In a standard positional numeral system, the base b is a positive integer, and b different numerals are used to represent all non-negative integers. Each numeral represents one of the values 0, 1, 2, etc., up to b − 1, but the value is weighted according to the position of the digit in a number. The value of a digit string like pqrs in base b is given by the polynomial form p × b 3 + q × b 2 + r × b + s {\displaystyle p\times b^{3}+q\times b^{2}+r\times b+s}. The numbers written in superscript represent the powers of the base used. For instance, in hexadecimal b =16, using the numerals A for 10, B for 11 etc., the digit string 7A3F means 7 × 16 3 + 10 × 16 2 + 3 × 16 + 15 {\displaystyle 7\times 16^{3}+10\times 16^{2}+3\times 16+15}, which written in our normal decimal notation is 31295. Upon introducing a radix point ". and a minus sign "−", all real numbers can be represented.

This article summarizes the facts on some non-standard positional numeral systems. In most cases, polynomial form in the description of the standard system still applies.

Some historical number systems can be called non-standard positional numeral systems. E. G., in the Babylonian sexagesimal notation and the Chinese rod numerals, which may be classified as a standard system base 60 and 10, respectively, considering the space representing a zero digit, can also be classified as non-standard systems, more specifically, a mixed base system with single components, considering the primitive recurring characters that make up the numbers.

However, most non-standard systems listed below were never intended for General use, but was developed by mathematicians or by engineers for special scientific or technical purposes.

## 1. Bijective numeration systems. (Систем биективных нумерация)

The bijective numeral system with base B uses b different numerals to represent all non-negative integers. However, these numbers have values of 1, 2, 3, etc. up to B, a zero represents a null digit string. For example, it is possible to have a decimal number without a leading zero.

### 1.1. Bijective numeration systems. Base one unary numeral system. (Основание одной унарной системе счисления)

Unary is the bijective numeral system with base b = 1. In unary, one numeral is used to denote all positive integers. The value of the digit string is recommended given the polynomial form can be simplified to p m R z s b p = 1 for all N. non-standard functions of this system include:

• The value 0 cannot be represented or is implicitly represented by an empty digit string.
• The value of a digit does not depend on its position. Thus, one can easily argue that unary is not a positional system at all.
• Introducing a radix point in this system will not enable representation of non-integer values.
• The single numeral represents the value 1, not the value 0 = b − 1.

## 2. Signed-digit representation. (Подпись-значное представление)

In some systems, while the base is a positive number, negative numbers are not allowed. Non-adjacent form is a special system, where the base B = 2. In the balanced ternary system, the base b = 3, and the digits have the values -1, 0 and 1.

## 3. Gray code. (Код Грея)

The reflected binary code also known as gray code that are closely related to binary numbers, but some bits are inverted, depending on the parity bits of the highest order.

### 4.1. Bases that are not positive integers. Negative base. (Отрицательной базы)

Negative-base systems include negabinary, negaternary and negadecimal, with bases -2, -3 and -10, respectively, in base − b the number of different digits is equal to B. due to the properties of negative numbers raised to the powers of all integers, positive and negative can be represented without a sign.

### 4.2. Bases that are not positive integers. Complex base. (Комплексная база)

In purely imaginary base BI, where b is a integer greater than 1 and I is an imaginary number, B 2 digit from 0 to B 2 − 1 are used as digits. Thus, the symbols used are not the same as the base. It can be generalized to other complex bases, formed the basis for the complex-based system.

### 4.3. Bases that are not positive integers. Non-integer base. (Нецелое основание)

In non-integer bases, the number of different digits clearly cannot be B. Instead, the numbers from 0 to ⌊ B ⌋ {\the style property display the value of a \lfloor b\rfloor } are used. For example, the Golden ratio base phinary, uses 2 different digits 0 and 1.

## 5. Mixed bases. (Смешанные основы)

It is sometimes convenient to consider positional numeral systems the weight associated with positions do not form a geometric progression 1, b 2, B 3, etc. starting from the least significant position, as specified in polynomial form. In a mixed radix system such as the radix factor weights form a sequence where each weight is a multiple of the previous one, and the number of allowed numeric values varies respectively from position to position.

To use the calendar Maya number system was a mixed-number system, since one of the positions is a multiplication by 18 rather than 20, to meet the 360-day calendar. Besides giving an angle in degrees, minutes, and seconds with a decimal, or time in days, hours, minutes and seconds, can be interpreted as mixed notation system.

A sequence where each weight is not a multiple of the previous weight may also be used, but then each integer can not have a unique representation. For example, the encoding of the Fibonacci numbers are 0 and 1, weighted in accordance with the Fibonacci sequence 1, 2, 3, 5, 8., a unique view of all non-negative integers can be achieved by the prohibition of consecutive 1S. Binary coded decimal BCD mixed base system, where bits binary digits are used to Express decimal numbers. E. G., in 1001 0011, each group of four bits can represent decimal in this example, the numbers 9 and 3, i.e., eight bits represent a decimal 93. The weights associated with these 8 positions 80, 40, 20, 10, 8, 4, 2 and 1. The uniqueness is ensured by the requirement that in each group of four bits if the first bit is 1, the following two must be 00.

## 6. Asymmetric numeral systems. (Асимметричные системы счисления)

Asymmetric numeral systems is the system used in computer science, where each digit may have a different base, as a rule, not an integer. They not only lie at the basis of this figures are different, they can also be uneven and asymmetric changes in a more efficient way of encoding information. They are optimized for the chosen heterogeneous distribution of probabilities of symbols, using an average of the Shannon entropy bits per symbol.
