Efficient way to determine number of digits in an integer
...For added efficiency, if you know that your input numbers will be mostly small ones (I'm guessing less than 100,000), then reverse the tests: if (x < 10) return 1; if (x < 100) return 2; etc., so that the function will do less tests and exit faster.

Use ^ on merge commits — because they have two or more (immediate) parents
