Decimal system (base 10)

The decimal number system is the standard and most commonly used system in everyday life. This numbering system uses the number 10 as the base. The decimal system includes 10 characters, which are numbers from 0 to 9. Specifically, 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9.

One of the oldest known number systems, the decimal number system was used by many ancient civilizations. The difficulty in expressing very large numbers in the decimal system was overcome by the Hindu-Arabic number system. The Hindu-Arabic numbering system provides the positions for the digits in a number. Each position is equivalent to a power of 10, starting with the rightmost position before the decimal point which is 100.

Numerical example 2345.67 in decimal:

  • The digit 5 ​​is in the units place (100 = 1),
  • The digit 4 is in the tens place (101)
  • The digit 3 is in the hundreds place (102)
  • The digit 2 is in the thousands place (103)
  • Meanwhile, the digit 6 after the decimal point is in the 1/10 position (10-1) and 7 is at the 1/100 position (10-2).

Therefore, no 2345.67 can also be represented as follows: (2 * 103) + (3 * 102) + (4 * 101) + (6 * 10-1) + (7 * 10-2).
