Convert.ToDouble Method (Byte)

Converts the value of the specified 8-bit unsigned integer to the equivalent double-precision floating point number.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

public static double ToDouble(
	byte value
)

Parameters

value
Type: System.Byte
An 8-bit unsigned integer.

Return Value

Type: System.Double
The double-precision floating point number equivalent to the value of value.

The following code sample illustrates the conversion of a Byte value to a Double one, using ToDouble.


public void ConvertDoubleByte(double doubleVal)
{
   byte byteVal = 0;

   // Double to byte conversion can overflow.
   try
   {
      byteVal = System.Convert.ToByte(doubleVal);
      outputBlock.Text += String.Format("{0} as a byte is: {1}.",
         doubleVal, byteVal) + "\n";
   }
   catch (System.OverflowException)
   {
      outputBlock.Text += String.Format(
         "Overflow in double-to-byte conversion.") + "\n";
   }

   // Byte to double conversion cannot overflow.
   doubleVal = System.Convert.ToDouble(byteVal);
   outputBlock.Text += String.Format("{0} as a double is: {1}.",
      byteVal, doubleVal) + "\n";
}
