Is There a More Concise Way to Count Integer Digits Than Using Strings?

Neatly Determining Integer Digit Count

Question:

Is there a more concise method for determining the number of digits in an integer than converting it to a string and getting its length?

int numDigits = String.valueOf(1000).length();

Answer:

Your string-based approach is not untidy. Recognize that numbers lack a mathematical length or digits. These qualities are inherent in a number's physical representation within a particular base (e.g., a string).

A logarithmic approach mirrors the string-based one internally and may be marginally quicker since it solely calculates the length without extracting the digits. However, its clarity of purpose is questionable. The primary consideration is the solution's clarity of intent.
