happy number In number theory, a happy number is a number which eventually reaches 1 when replaced by the sum of the square of each digit. For instance, 13 is a happy number because 1^2+3^2=10, and 1^2+0^2=1. On the other hand, 4 is not a happy number because ...

, meaning that repeatedly summing the squares of its digits eventually leads to 1: 888 →64+64+64= 192→1+81+4= 86→64+36=100→1
