The number 2 {\displaystyle \scriptstyle {\sqrt {2}}} is irrational. In mathematics, an irrational number is a real number that cannot be expressed as a ratio of integers, i.e. as a fraction. Therefore, irrational numbers, when written as decimal numbers, do not terminate, nor do they repeat.
Part of the Mathematics glossary: A transcendental number is a real number that is not the solution of any single-variable polynomial equation whose coefficients are all integers. All transcendental numbers are irrational numbers. But the converse is not true; there are some irrational numbers that are not transcendental. Examples of transcendental numbers include pi, the ratio of a circle's circumference to its diameter in a plane, and e, the base of the natural logarithm. The case of pi has historical significance.
