An irrational number is a number that cannot be expressed as a ratio of two integers.
The word "irrational" as used here refers to "not expressable as a ratio", and does not mean insane.
Irrational numbers include non-repeating, non-terminating decimals, for example, the square root of any number that is not a perfect square.
Some examples would be:

The base of natural logarithms.
