'Usage
 
Dim input() As Integer
Dim precision As Byte
Dim scale As Byte
 
Dim instance As New TdDecimal(input, precision, scale)

public TdDecimal( 
   int[] input,
   byte precision,
   byte scale
)

public:
TdDecimal( 
   array<int>^ input,
   byte precision,
   byte scale
)

Parameters

input

Array that contains the internal representation of the number.

precision

Precision of the number.

scale

Scale of the number.

TdDecimal uses four 32 bit integers to internally store the number. The four integers will represent the decimal as a scaled 128 bit integer --the decimal point has been removed by multiplying the number by 10 to the power of the scale. This decimal is stored this way because it is very easy to perform operation on the decimal. The precision and scale are stored separately within TdDecimal.

The array that is passed in will have 4 elements which are the number components of the internal representation of the TdDecimal:

• data[0] will contain the low order bits
• data[2 and 3] consist of the middle order bits
• data[4] contains the high order bits

The following is an example of setting up the array with a number, and then invoking the constructor.

// Decimal Number:          82985000914920.733988
// Hex Representation:      4 7FA5F2A8 A350FD24
Int32 [] numberComponents01 = {unchecked((Int32)0xA350FD24), (Int32)0x7FA5F2A8, (Int32)0x00000004, 0};
TdDecimal value01 = new TdDecimal(numberComponents01, 20, 6);
            
// Decimal Number:      -1
// Hex Representation:  FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF (two's compliment form)
Int32 [] numberComponents02 = {unchecked((Int32)0xFFFFFFFF), unchecked((Int32)0xFFFFFFFF),
                               unchecked((Int32)0xFFFFFFFF), unchecked((Int32)0xFFFFFFFF)};
TdDecimal value02 = new TdDecimal(numberComponents02, 1, 0);
