A rational or irrational number, can have a decimal representation with an infinite number of digits after the decimal point.

Usual numbers generally have periodic decimal expansion (a series of digits that repeats), but there are an infinity of numbers with an infinity of digits after the decimal point.

Generally, if the number is a relatively random universe number (like π or e or phi, even if it is a conjecture) then it is not possible to predict the position of a number or pattern of digits, the only mean is to browse them in the order.

Example: Search birth date '18/08/1998 'in pi, found in position 794769.

For dCode, the first decimal 1 in pi = 3.14159 is in position 1. Other programs use position 0, or position 2 (the digit 3 before the decimal point/dot is then considered as position 1).

dCode knows the decimals up to 1000000 (one million) digits.

A disjuctive number (rich number or universe number) is defined as a real number whose representation contains any combination of numbers.

Mathematicians believe that irrational constants such as $ \pi $ or $ \sqrt{2} $ are universe numbers but this has not yet been proven.
