Decimal.ToDouble() Method in C#

This method is used to convert the value of the specified Decimal to the equivalent double-precision floating-point number. This method can produce round-off errors as a double-precision floating-point number has few significant digits than a Decimal.

Syntax: public static double ToDouble (decimal d);
Here, d is the decimal value which is to be converted.

Return value: It returns a double-precision floating-point number equivalent to d.






// C# program to demonstrate the
// Decimal.ToDouble(Decimal) Method
using System;
class GFG {
    // Main Method
    public static void Main()
        try {
            // Taking decimal variables
            Decimal dec1 = 0.0000000000134563456789M;
            Decimal dec2 = 4589662514452860951234M;
            // using ToDouble(Decimal) Method
            Double val1 = Decimal.ToDouble(dec1);
            // using ToDouble(Decimal) Method
            Double val2 = Decimal.ToDouble(dec2);
            // Printing the Double value
            Console.WriteLine("The Double value "
                              + "is : {0}", val1);
            // Printing the Double value
            Console.WriteLine("The Double value "
                              + "is : {0}", val2);
        catch (OverflowException e) 
            Console.Write("Exception Thrown: ");
            Console.Write("{0}", e.GetType(), e.Message);



The Double value is : 1.34563456789E-11
The Double value is : 4.58966251445286E+21
