Irrational Numbers are used in some scientific jobs. Commonly used irrational numbers are pi, e, and square roots of different numbers. Of course, if an actual numerical result has to be calculated, the irrational number is rounded to some rational (usually decimal) approximation.

What are the application of irrational numbers?
Oh honey, irrational numbers are used in all sorts of fun ways! From calculating the diagonal of a square to measuring the circumference of a circle, these quirky numbers pop up everywhere in math and science. So next time you come across a pesky square root or a never-ending decimal, just remember that irrational numbers are here to keep things interesting.
What is the sign for a never-ending number?
"never-ending number" is ambiguous. You could either mean an infinite number, or an irrational number. For infinite numbers, you could use the Hebrew letter Aleph - which is used to represent the cardinal numbers of infinite sets of finite numbers. For irrational numbers, as far as I know there is no commonly accepted symbol to represent them.
Is the square root of 14 a natural number?
Natural numbers are those numbers used for counting. The square root of 14 is the irrational number 3.74165... . Therefore, the square root of 14 is not a natural number.
Is 3.14159 a rational or irrational number?
3.14159 is rational. However, it is often used as an approximation for π, which is irrational. It is important to recognise that the rational number, 3.14159, is only an approximation for π.
What is a a surd?
A surd is when an irrational number (a non square number under a square root sign) is simplified for accuracy and ease of legibility.E.G:√5 x √2 = √10There are no such rational numbers as Square root of five or two so when we multiply them (as shown in the exampke above) we show the answer in surd form for simplicity, accuracy and legibility.
