Tool to calculate the digital root of a number. The digital root is computed using recursive reduction that consists in performing the sum of all digits in a number and repeat this operation on the result.

A numeric root is the sum of the digits of a number repeated until a single digit is obtained.

Digital root calculation uses recursive reduction that consists in repeating the operation of summing/adding digits until the result has only one digit.

__Example:__ 789 => 7+8+9 = 24 => 2+4 = 6

This principle is often used in numerology to get a number from the numeric information on an individual (from a date of birth, favorite number, etc.)

__Example:__ 25/12/2000 => 2 + 5 + 1 + 2 + 2 + 0 + 0 + 0 = 12 => 1 + 2 = 3

In mathematics, the calculation of the numerical root is used when casting out 9s.

In numerology, the number root is used for anything and everything.

It is possible to assign a value to a name using the position of letters in the alphabet (see A1Z26 code where A = 1, B = 2, … Z = 26) then make the desired additions and analyze the total.

__Example:__ `DCODE` = 4,3,15,4,5 and 4+3+15+4+5 = 31 => 3+1 = 4

(variant) `DCODE` = 4,3,15,4,5 and 4+3+1+5+4+5 = 22 => 2+2 = 4
