Kümnendkujund

Kümnendkujund, a term originating from Estonian, translates to "decimal figure" or "decimal representation." It refers to the way a number is written using the decimal system, which is a positional numeral system with a base of 10. In this system, each digit's position represents a power of 10. The digits used are 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9.

The decimal system is the most common system used worldwide for everyday arithmetic and notation. A kümnendkujund can represent both whole numbers and fractional parts. The digits to the left of the decimal point (or comma, in some European conventions) represent the integer part, with positions indicating units, tens, hundreds, and so on. The digits to the right of the decimal point represent the fractional part, with positions indicating tenths, hundredths, thousandths, and so forth.

For instance, the number 123.45 is a kümnendkujund. Here, '1' is in the hundreds place, '2' is in the tens place, '3' is in the units place, '4' is in the tenths place, and '5' is in the hundredths place. This representation allows for expressing any real number with arbitrary precision, although in practical applications, the number of decimal places is often limited. The concept is fundamental to mathematics and is used in various fields, including science, engineering, and finance, for measurement, calculation, and data representation.
