Irrational number

Irrational Number, News

In mathematics, an irrational number is a number that cannot be expressed as a fraction of two integers, which means it cannot be written in the form a/b where a and b are integers and b is not zero. Irrational numbers are often referred to as non-terminating, non-repeating decimals because their decimal representations neither terminate nor repeat. The most famous example of an irrational number is the square root of 2, which is approximately 1.414.

  • Non-terminating, non-repeating decimals: Irrational numbers have decimal representations that never end and never repeat. This is in contrast to rational numbers, which have decimal representations that either terminate or repeat.
  • Cannot be expressed as a fraction of two integers: Irrational numbers cannot be expressed as a fraction of two integers. This means that they cannot be represented as a/b, where a and b are integers and b is not zero.
  • Examples: Examples of irrational numbers include the square root of 2, the golden ratio, and pi.
