eikokonaisluvut

Eikokonaisluvut, also known as non-integers, represent numbers that are not whole numbers. This category encompasses a wide range of numerical values. The most common examples of eikokonaisluvut are fractions and decimals. Fractions, such as 1/2 or 3/4, express a part of a whole. Decimals, like 0.5 or 3.14, use a base-ten positional notation system where a decimal point separates the whole number part from the fractional part.

The set of eikokonaisluvut includes rational numbers and irrational numbers. Rational numbers can be expressed as a ratio of two integers, where the denominator is not zero. This means all terminating and repeating decimals are rational. For instance, 0.75 is rational because it can be written as 3/4, and 0.333... is rational as it's equivalent to 1/3. Irrational numbers, on the other hand, cannot be expressed as a simple fraction. Their decimal representations are non-terminating and non-repeating. Famous examples of irrational numbers include pi (π) and the square root of 2.

The concept of eikokonaisluvut is fundamental in mathematics, forming a crucial part of the real number system. They are used extensively in measurement, calculation, and various scientific and engineering disciplines. Understanding the distinction between eikokonaisluvut and kokonaisluvut (integers) is essential for comprehending mathematical operations and concepts.
