Way to get number of digits in an int?

Question

Is there a neater way for getting the number of digits in an int than this method?

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

Answer 1

Try converting the int to a string and then get the length of the string. That should get the length of the int.

public static int intLength(int num){
    String n = Integer.toString(num);
    int newNum = n.length();
    return newNum;
}
