Kümnendväärtus

Kümnendväärtus refers to the value of a number expressed using the decimal system. It is the standard way of representing numbers in everyday life, using a base-10 numeral system. This system employs ten distinct digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. The position of each digit within a number determines its place value, which is a power of 10. For example, in the number 123.45, the digit 1 represents one hundred (10^2), the digit 2 represents twenty (2 * 10^1), the digit 3 represents three (3 * 10^0), the digit 4 represents four tenths (4 * 10^-1), and the digit 5 represents five hundredths (5 * 10^-2).

The decimal system originated in India and was transmitted to the Western world through Arab mathematicians, hence it is also often referred to as the Hindu-Arabic numeral system. Its widespread adoption is due to its simplicity and efficiency in performing arithmetic operations. The concept of zero as a placeholder and a number in its own right is crucial to the functionality of the decimal system, allowing for unambiguous representation of numbers regardless of their magnitude. When discussing approximations or measurements, the term kümnendväärtus can also refer to the significant digits or the precision of a given value.
