Mittetäisarvuliste

Mittetäisarvuliste refers to numbers that are not integers. Integers are whole numbers, including positive numbers, negative numbers, and zero. Examples of integers are -3, 0, 15, and 1000.

Mittetäisarvuliste include all numbers that fall between integers. This category encompasses a vast range of numbers. The most common examples of mittetäisarvuliste are fractions and decimals. Fractions represent parts of a whole, such as 1/2, 3/4, or -5/8. Decimals represent numbers that have a fractional part expressed using a decimal point, such as 0.5, 3.14, or -2.75.

Rational numbers are a subset of mittetäisarvuliste, meaning they can be expressed as a fraction p/q, where p and q are integers and q is not zero. This includes all terminating and repeating decimals. However, there are also irrational numbers, which are also mittetäisarvuliste, but cannot be expressed as a simple fraction. Famous examples of irrational numbers include pi (π) and the square root of 2 (√2). Their decimal representations neither terminate nor repeat.

The set of all real numbers comprises both integers and mittetäisarvuliste. Understanding the distinction between these number types is fundamental in mathematics, particularly in areas like algebra, calculus, and number theory. When a problem requires precision or involves quantities that can be divided into parts, mittetäisarvuliste are essential for accurate representation and calculation.
