digit count of number as lambda

[bluefrog]

Is it possible to make the function below into a lambda?

int digit_count(int number) {
  int digits = 0;
  if (number < 0) digits = 1; // remove this line if '-' counts as a digit
  while (number) {
      number /= 10;
      digits++;
  }
  return digits;
}

As far as I know, you can turn pretty much any function into a lambda.

auto dc_lambda =
    []( int number )
    {
        int digits = 0;
        if (number < 0) digits = 1; // remove this line if '-' counts as a digit
        while (number) {
            number /= 10;
            digits++;
        }
        return digits;
    };
