kümnendnumber

A kümnendnumber, often translated as "decimal number," is a numeral system where each digit's value is determined by its position relative to a decimal point. This system is based on the number ten, meaning there are ten unique digits used: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9.

The decimal point, also known as the radix point, is the crucial separator in a kümnendnumber. Digits to the left of the decimal point represent whole units, with their place value increasing by powers of ten as you move further left (ones, tens, hundreds, thousands, and so on). Digits to the right of the decimal point represent fractional parts, with their place value decreasing by powers of ten as you move further right (tenths, hundredths, thousandths, etc.).

For example, in the number 123.45, the '1' is in the hundreds place, the '2' is in the tens place, the '3' is in the ones place, the '4' is in the tenths place, and the '5' is in the hundredths place. This positional notation allows for the representation of any real number, whether it is an integer or a fraction, with a finite or repeating sequence of digits. The kümnendnumber system is the most common number system used globally for everyday calculations and scientific endeavors.
