@GwtIncompatible // Floats.tryParse
public void testTryParseOfToHexStringIsOriginal() {
 for (float f : NUMBERS) {
  checkTryParse(f, Float.toHexString(f));
 }
}

private void transformA(StringBuilder result) {
  if (arg instanceof Float) {
    result.append(Float.toHexString(((Float) arg).floatValue()));
  } else if (arg instanceof Double) {
    result.append(Double.toHexString(((Double) arg).doubleValue()));
  } else {
    throw badArgumentType();
  }
  if (!formatToken.isPrecisionSet()) {
    return;
  }
  int precision = formatToken.getPrecision();
  if (precision == 0) {
    precision = 1;
  }
  int indexOfFirstFractionalDigit = result.indexOf(".") + 1;
  int indexOfP = result.indexOf("p");
  int fractionalLength = indexOfP - indexOfFirstFractionalDigit;
  if (fractionalLength == precision) {
    return;
  }
  if (fractionalLength < precision) {
    char[] zeros = new char[precision - fractionalLength];
    Arrays.fill(zeros, '0'); // %a shouldn't be localized.
    result.insert(indexOfP, zeros);
    return;
  }
  result.delete(indexOfFirstFractionalDigit + precision, indexOfP);
}
