* To avoid erroneous double-rounding or truncation when converting

* rounding done, is needed in this class.
*
* - For the HALF_DOWN, HALF_EVEN, HALF_UP rounding rules below:
* In the case of formating float or double, We must take into
* account what FloatingDecimal has done in the binary to decimal
* conversion.
*
* Considering the tie cases, FloatingDecimal may round-up the
* value (returning decimal digits equal to tie when it is below),
* or "truncate" the value to the tie while value is above it,
* or provide the exact decimal digits when the binary value can be
* converted exactly to its decimal representation given formating
* rules of FloatingDecimal ( we have thus an exact decimal
* representation of the binary value).
*
* - If the double binary value was converted exactly as a decimal
* value, then DigitList code must apply the expected rounding
* rule.
*
* - If FloatingDecimal already rounded up the decimal value,
* DigitList should neither round up the value again in any of
* the three rounding modes above.
*
* - If FloatingDecimal has truncated the decimal value to
* an ending '5' digit, DigitList should round up the value in
* all of the three rounding modes above.
*
*
* This has to be considered only if digit at maximumDigits index
* is exactly the last one in the set of digits, otherwise there are
* remaining digits after that position and we dont have to consider
* what FloatingDecimal did.
*
* - Other rounding modes are not impacted by these tie cases.
*
* - For other numbers that are always converted to exact digits
* (like BigInteger, Long, ...), the passed alreadyRounded boolean
* have to be set to false, and allDecimalDigits has to be set to
* true in the upper DigitList call stack, providing the right state
* for those situations..
