    Description copied from interface: DecimalArithmetic
    
    Returns an unscaled decimal whose value is the inverse of the argument: 1/uDecimal. If rounding must be performed, this arithmetic's rounding mode is applied.
    Mathematically the method calculates round((10^scale * 10^scale) / uDecimalDivisor) avoiding information loss due to overflow of intermediary results.

  - pow
```
public final long pow(long uDecimal,
                      int exponent)
```
    Description copied from interface: DecimalArithmetic
    Returns an unscaled decimal whose value is (uDecimalBase^exponent). Note that exponent is an integer rather than a decimal. If rounding must be performed, this arithmetic's rounding mode is applied.
    The current implementation uses the core algorithm defined in ANSI standard X3.274-1996. For exponent >= 0, the returned numerical value is within 1 ULP of the exact numerical value; the result is actually exact for all rounding modes other than HALF_UP, HALF_EVEN and HALF_DOWN. No precision is guaranteed for exponent < 0 but the result is usually exact up to 10-20 ULP.
    Properties of the X3.274-1996 algorithm are:
    - An IllegalArgumentException is thrown if abs(n) > 999999999
    - if exponent is zero, one is returned even if uDecimalBase is zero, otherwise
      
      if exponent is positive, the result is calculated via the repeated squaring technique into a single accumulator
      
      if exponent is negative, the result is calculated as if exponent were positive; this value is then divided into one
      
      The final value from either the positive or negative case is then rounded using this arithmetic's rounding mode
    Note: this operation is not strictly garbage free since internally, two ThreadLocal objects are used to calculate the result. The ThreadLocal values may become garbage if the thread becomes garbage.
    Parameters:
    
    uDecimal - the unscaled decimal base value
    
    exponent - exponent to which uDecimalBase is to be raised.
    
    Returns:
    
    uDecimalBase^exponent

```
    Description copied from interface: DecimalArithmetic
    
    Returns an unscaled decimal whose value is (uDecimal << n). The shift distance, n, may be negative, in which case this method performs a right shift. The result is equal to round(uDecimal * 2ⁿ) using this arithmetic's rounding mode if rounding is necessary.

```
    Description copied from interface: DecimalArithmetic

    Description copied from interface: DecimalArithmetic
    
    Converts the specified unscaled decimal value into a double value and returns it. The arithmetic's rounding mode is applied if rounding is necessary.
    
    Parameters:
    
    uDecimal - the unscaled decimal value to convert into a double value
    
    Returns:
    
    the uDecimal value converted into a double value, possibly rounded or truncated

public final long parse(String value)
```
    Description copied from interface: DecimalArithmetic
    
    Translates the string representation of a Decimal into an unscaled Decimal. The string representation consists of an optional sign, '+' or '-' , followed by a sequence of zero or more decimal digits ("the integer"), optionally followed by a fraction.
    The fraction consists of a decimal point followed by zero or more decimal digits. The string must contain at least one digit in either the integer or the fraction. If the fraction contains more digits than this arithmetic's scale, the value is rounded using the arithmetic's rounding mode. An exception is thrown if the value is too large to be represented as a Decimal of this arithmetic's scale.
    
    Parameters:
    
    value - a String containing the decimal value representation to be parsed
    
    Returns:
    
    the decimal as unscaled long value
  - parse

An exception is thrown if the value is too large to be represented as a Decimal of this arithmetic's scale.
    
    Parameters:
    
    value - a character sequence such as a String containing the decimal value representation to be parsed
    
    start - the start index to read characters in value, inclusive
    
    end - the end index where to stop reading in characters in value, exclusive
    
    Returns:
    
    the decimal as unscaled long value
