Answers to Questions

How to find a pattern in decimal places of a number?

Generally, if the number is a relatively random universe number (like π or e or phi) 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 for the first decimal 1 in 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.

What is a disjuctive number?

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.
