  System.Decimal Structure
 
 Description
Calling writeTextBlock The Decimal structure is explicitly designed to hold very large numbers with a large number of significant digits, as required by financial applications - no errors can be created by rounding.
 
Internally, the number is held in 3 parts :
 
Sign + or -
Mantissa A 96 bit number, holding the significant digits
Exponent 0 to 28 decimal places

 
The range of numbers supported is given in the MinValue and MaxValue fields below.
 
The Array of Int32 constructor provides the decimal value in 4 Int32 values :
 
Array[0] Low order 32 bits of the 96 bit mantissa
Array[1] Mid order 32 bits of the 96 bit mantissa
Array[2] High order 32 bits of the 96 bit mantissa
Array[3] Bits 16-23 contain the exponent, bit 31 the sign

 
Likewise, the final constructor allows a piecemeal build of the decimal value. After writeTextBlock
 Syntax
Constructor Create ( Value : Int16 );
Constructor Create ( Value : Int32 );
Constructor Create ( Value : UInt16 );
Constructor Create ( Value : UInt32 );
Constructor Create ( Value : Single );
Constructor Create ( Value : Double );
Constructor Create ( Values : Array of Int32 );
Constructor Create ( Low : Int32; Mid : Int32; High : Int32; IsNegative : Boolean; Exponent : Byte );
