   * representable as a double, but {@code roundToDouble(BigDecimal.valueOf(2).pow(2000), HALF_UP)}
   * will return {@code Double.MAX_VALUE}, not {@code Double.POSITIVE_INFINITY}.

 *     String value = header.getValue();
 *     boolean isValid = header.isValid();

 *
 * <p>Note: The name should not be blank and the value should not be null for the header to be considered valid.</p>
