    Negative zero and positive zero are considered equal.
    
    Quiet NaN has a higher "absolute value" than signaling NaN. If both objects are quiet NaN or both are signaling NaN, the one with the higher diagnostic information has a greater "absolute value".
    
    NaN has a higher "absolute value" than infinity.

    ec - An arithmetic context to control the precision, rounding, and exponent range of the result. Can be null.
    
    Returns:
    
    An arbitrary-precision number with the same value as this one but with certain trailing zeros removed from its mantissa. If ed1 is not-a-number (NaN) or infinity, it is generally returned unchanged.
  - Rescale
```
public static EDecimal Rescale(EDecimal ed,
                               EDecimal scale,
                               EContext ec)
```
    Returns an arbitrary-precision decimal number with the same value as this object but with the given exponent, expressed as an arbitrary-precision decimal number.
    Note that this is not always the same as rounding to a given number of decimal places, since it can fail if the difference between this value's exponent and the desired exponent is too big, depending on the maximum precision. If rounding to a number of decimal places is desired, it's better to use the RoundToExponent and RoundToIntegral methods instead.
    
    Remark: This method can be used to implement fixed-point decimal arithmetic, in which a fixed number of digits come after the decimal point. A fixed-point decimal arithmetic in which no digits come after the decimal point (a desired exponent of 0) is considered an "integer arithmetic" .
    
    Parameters:
    
    ed - An arbitrary-precision decimal number whose exponent is to be changed.
    
    scale - The desired exponent of the result, expressed as an arbitrary-precision decimal number. The exponent is the number of fractional digits in the result, expressed as a negative number. Can also be positive, which eliminates lower-order places from the number. For example, -3 means round to the thousandth (10^-3, 0.0001), and 3 means round to the thousands-place (10^3, 1000). A value of 0 rounds the number to an integer.
    
    ec - The parameter ec is an EContext object.
    
    Returns:
    
    An arbitrary-precision decimal number with the same value as this object but with the exponent changed. Signals FlagInvalid and returns not-a-number (NaN) if the result can't fit the given precision without rounding, or if the arithmetic context defines an exponent range and the given exponent is outside that range.
  - And
```
public static EDecimal And(EDecimal ed1,
                           EDecimal ed2,
                           EContext ec)
```
    Performs a logical AND operation on two decimal numbers in the form of logical operands . A logical operand is a non-negative base-10 number with an Exponent property of 0 and no other base-10 digits than 0 or 1 (examples include 01001 and 111001 , but not 02001 or 99999). The logical AND operation sets each digit of the result to 1 if the corresponding digits of each logical operand are both 1, and to 0 otherwise. For example, 01001 AND 111010 = 01000 .
    
    Parameters:
    
    ed1 - The first logical operand to the logical AND operation.
    
    ed2 - The second logical operand to the logical AND operation.
    
    ec - An arithmetic context to control the maximum precision of arbitrary-precision numbers. If a logical operand passed to this method has more digits than the maximum precision specified in this context, the operand's most significant digits that exceed that precision are discarded. This parameter can be null.
    
    Returns:
    
    The result of the logical AND operation as a logical operand. Signals an invalid operation and returns not-a-number (NaN) if ed1 , ed2 , or both are not logical operands.
  - Invert
```
public static EDecimal Invert(EDecimal ed1,
                              EContext ec)
```
    Performs a logical NOT operation on an arbitrary-precision decimal number in the form of a logical operand . A logical operand is a non-negative base-10 number with an Exponent property of 0 and no other base-10 digits than 0 or 1 (examples include 01001 and 111001 , but not 02001 or 99999). The logical NOT operation sets each digit of the result to 1 if the corresponding digit is 0, and to 0 otherwise; it can set no more digits than the maximum precision, however. For example, if the maximum precision is 8 digits, then NOT 111010 = 11000101 .
    
    Parameters:
    
    ed1 - The logical operand to the logical NOT operation.
    
    ec - An arithmetic context to control the maximum precision of arbitrary-precision numbers. If a logical operand passed to this method has more digits than the maximum precision specified in this context, the operand's most significant digits that exceed that precision are discarded. This parameter cannot be null and must specify a maximum precision (unlimited precision contexts are not allowed).
    
    Returns:
    
    The result of the logical NOT operation as a logical operand. Signals an invalid operation and returns not-a-number (NaN) if ed1 is not a logical operand.
  - Xor
```
public static EDecimal Xor(EDecimal ed1,
                           EDecimal ed2,
                           EContext ec)
```
    Performs a logical exclusive-OR (XOR) operation on two decimal numbers in the form of logical operands . A logical operand is a non-negative base-10 number with an exponent of 0 and no other base-10 digits than 0 or 1 (examples include 01001 and 111001 , but not 02001 or 99999). The logical exclusive-OR operation sets each digit of the result to 1 if either corresponding digit of the logical operands, but not both, is 1, and to 0 otherwise. For example, 01001 XOR 111010 = 101010 .
    
    Parameters:
    
    ed1 - The first logical operand to the logical exclusive-OR operation.
    
    ed2 - The second logical operand to the logical exclusive-OR operation.
    
    ec - An arithmetic context to control the maximum precision of arbitrary-precision numbers. If a logical operand passed to this method has more digits than the maximum precision specified in this context, the operand's most significant digits that exceed that precision are discarded. This parameter can be null.
    
    Returns:
    
    An EDecimal object.
  - Or
```
public static EDecimal Or(EDecimal ed1,
                          EDecimal ed2,
                          EContext ec)
```
    Performs a logical OR operation on two decimal numbers in the form of logical operands . A logical operand is a non-negative base-10 number with an Exponent property of 0 and no other base-10 digits than 0 or 1 (examples include 01001 and 111001 , but not 02001 or 99999). The logical OR operation sets each digit of the result to 1 if either or both of the corresponding digits of the logical operands are 1, and to 0 otherwise. For example, 01001 OR 111010 = 111011 .
    
    Parameters:
    
    ed1 - The first logical operand to the logical OR operation.
    
    ed2 - The second logical operand to the logical OR operation.
    
    ec - An arithmetic context to control the maximum precision of arbitrary-precision numbers. If a logical operand passed to this method has more digits than the maximum precision specified in this context, the operand's most significant digits that exceed that precision are discarded. This parameter can be null.
    
    Returns:
    
    The result of the logical OR operation as a logical operand. Signals an invalid operation and returns not-a-number (NaN) if ed1 , ed2 , or both are not logical operands.
