Decimal(Double)

Source:: Decimal.cs

Source:: Decimal.cs

Source:: Decimal.cs

Initializes a new instance of Decimal to the value of the specified double-precision floating-point number.

public:
 Decimal(double value);

public Decimal (double value);

new decimal : double -> decimal

Public Sub New (value As Double)

Parameters

value: Double

The value to represent as a Decimal.

Exceptions

OverflowException

value is greater than Decimal.MaxValue or less than Decimal.MinValue.

-or-

value is NaN, PositiveInfinity, or NegativeInfinity.

Examples

The following code example creates several Decimal numbers using the constructor overload that initializes a Decimal structure with a Double value.

// Example of the Decimal( double ) constructor.
using namespace System;

// Get the exception type name; remove the namespace prefix.
String^ GetExceptionType( Exception^ ex )
{
   String^ exceptionType = ex->GetType()->ToString();
   return exceptionType->Substring( exceptionType->LastIndexOf( '.' ) + 1 );
}


// Create a Decimal object and display its value.
void CreateDecimal( double value, String^ valToStr )
{
   
   // Format and display the constructor.
   Console::Write( "{0,-34}", String::Format( "Decimal( {0} )", valToStr ) );
   try
   {
      
      // Construct the Decimal value.
      Decimal decimalNum = Decimal(value);
      
      // Display the value if it was created successfully.
      Console::WriteLine( "{0,31}", decimalNum );
   }
   catch ( Exception^ ex ) 
   {
      
      // Display the exception type if an exception was thrown.
      Console::WriteLine( "{0,31}", GetExceptionType( ex ) );
   }

}

Remarks

This constructor rounds value to 15 significant digits using rounding to nearest. This is done even if the number has more than 15 digits and the less significant digits are zero.

Applies to

Decimal(Int32)

Source:: Decimal.cs

Source:: Decimal.cs

Source:: Decimal.cs

Initializes a new instance of Decimal to the value of the specified 32-bit signed integer.

public:
 Decimal(int value);

public Decimal (int value);

new decimal : int -> decimal

Public Sub New (value As Integer)

Parameters

value: Int32

The value to represent as a Decimal.

Applies to

Decimal(Int32[])

Source:: Decimal.cs

Source:: Decimal.cs

Source:: Decimal.cs

Initializes a new instance of Decimal to a decimal value represented in binary and contained in a specified array.

public:
 Decimal(cli::array <int> ^ bits);

public Decimal (int[] bits);

new decimal : int[] -> decimal

Public Sub New (bits As Integer())

Parameters

bits: Int32[]

An array of 32-bit signed integers containing a representation of a decimal value.

Exceptions

ArgumentNullException

bits is null.

ArgumentException

The length of the bits is not 4.

-or-

The representation of the decimal value in bits is not valid.

The following code example creates several Decimal numbers using the constructor overload that initializes a Decimal structure with an array of four Int32 values.

Remarks

The binary representation of a Decimal number consists of a 1-bit sign, a 96-bit integer number, and a scaling factor used to divide the integer number and specify what portion of it is a decimal fraction. The scaling factor is implicitly the number 10, raised to an exponent ranging from 0 to 28.

bits is a four-element long array of 32-bit signed integers.

bits [0], bits [1], and bits [2] contain the low, middle, and high 32 bits of the 96-bit integer number.

bits [3] contains the scale factor and sign, and consists of following parts:

Bits 0 to 15, the lower word, are unused and must be zero.

Bits 16 to 23 must contain an exponent between 0 and 28, which indicates the power of 10 to divide the integer number.

Bits 24 to 30 are unused and must be zero.

Bit 31 contains the sign; 0 meaning positive, and 1 meaning negative.

A numeric value might have several possible binary representations; all are equally valid and numerically equivalent. Note that the bit representation differentiates between negative and positive zero. These values are treated as being equal in all operations.

Initializes a new instance of Decimal from parameters specifying the instance's constituent parts.

public:
 Decimal(int lo, int mid, int hi, bool isNegative, System::Byte scale);

public Decimal (int lo, int mid, int hi, bool isNegative, byte scale);

new decimal : int * int * int * bool * byte -> decimal

Public Sub New (lo As Integer, mid As Integer, hi As Integer, isNegative As Boolean, scale As Byte)

Parameters

lo: Int32

The low 32 bits of a 96-bit integer.

mid: Int32

The middle 32 bits of a 96-bit integer.

hi: Int32

The high 32 bits of a 96-bit integer.

isNegative: Boolean

true to indicate a negative number; false to indicate a positive number.

scale: Byte

A power of 10 ranging from 0 to 28.

Exceptions

ArgumentOutOfRangeException

scale is greater than 28.

         Decimal newValue = new Decimal(parts[0], parts[1], parts[2], sign, scale);
         Console.WriteLine("{0} --> {1}", value, newValue);
      }
   }
}
// The example displays the following output:
