Tool to search digits or digits patterns (id number, birth date, etc.) in the decimals of some numbers (Pi, e, square root of 2 etc.)
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.
