Disadvantages of the binary system: Final decimal fractions can be written as infinite binary fractions the same number in binary notation has more digits than in decimal the representation of a number in the binary system is homogeneous, that is, it contains only zeros and ones therefore, it is difficult for a person to perceive it. Keep a note of the remainder, it should be between 0 and 15. Get the integer quotient for the next iteration (if the number will not divide equally by 16, then round down the result to the nearest whole number). Advantages of the binary system: we need technical devices with only two stable states (there is current - no current, magnetized - not magnetized, etc.) performing operations with binary numbers for a computer is much easier than with decimal numbers the addition and multiplication tables are much smaller in binary than in decimal. Follow these steps to convert a decimal number into hexadecimal form: Divide the decimal number by 16. When moving one position to the left, the value of the digit doubles. In the binary system, there are only two digits - zero and one. Decimal numeral system is a positional numeral system based on the integer base 10, which forms the unit of the 2nd digit, the unit of the 3rd digit will be 100 = 10 to the second power, in general, the unit of each next digit is 10 times more than the unit of the previous one.Īmong positional number systems, a special place is occupied by the binary number system. Moreover, the same sign (number) out of ten has different meanings depending on where it is located. To write numbers, the symbols 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 (Arabic numerals) are used.

The decimal number system is the most common number system in the world.

Number systems are divided into positional, non-positional and mixed. Number system is a symbolic method of writing numbers, representing numbers using written signs.
