Why should numbers be transferred from one system to another? If to write the number in the homogeneous of the 10th system, it is possible to use in each discharge only one digit in the range of 0 – 9, thus, allowed number of 450 (grade 1 st – 0, 2 nd – 5, 3 rd – 4), and 4F5 – not, as the letter F is not included in a set of digits from 0 to 9. As an example, we use the decimal system. The homogeneous system – for each category of the set of allowed symbols (digits) is the same. The number of different digits (characters) used in the positional numeral system for representing (record) number, is called the base. Rank number increases from right to left. The position of figure is called discharge. Positional system – the quantitative value of the numbers depends on its place in the entry number. Non positional system – some letters are used as digits. Numeral system is a collection of symbols (digits) and the rules of their use for numbers representation.
