digital root
The digital root of a positive integer is found by summing the digits of the integer. If the resulting value is a single digit then that digit is the digital root. ,The digital root (also repeated digital sum) of a non-negative integer is the (single digit) value obtained by an iterative process of summing digits, on each ... ,For example, the sequence obtained from the starting number 9876 in base 10 is (9876, 30, 3), so 9876 has an additive persistence of 2 and a digital root of 3. ,The digital root or digital sum of a non-negative integer is the single-digit value obtained by an iterative process of summing digits, on each iteration using the ... ,In this article for teachers, Bernard Bagnall describes how to find digital roots and suggests that they can be worth exploring when confronted by a sequence of ... ,In number theory, the multiplicative digital root of a natural number n -displaystyle n} n in a given number base b -displaystyle b} b is found by multiplying the ... , In this kata, you must create a digital root function. A digital root is the recursive sum of all the digits in a number. Given n, take the sum of the ...,在數學中，數根(又稱位數根或數字根Digital root)是自然數的一種性質，換句話說，每個自然數都有一個數根。 數根是將一正整數的各個位數相加（即橫向相加），若加完 ...
