Decimal.Floor() Method in C#

This method is used to round the decimal to the closest integer toward negative infinity.

Syntax: public static decimal Floor (decimal d);

Parameter:
d: This parameter specifies the decimal which will be rounded off.

Return Value: If d has a fractional part, the next whole Decimal number toward negative infinity that is less than d or d doesn’t have a fractional part, d is returned unchanged. Note that the method returns an integral value of type Decimal.

Below programs illustrate the use of Decimal.Floor(Decimal) Method:

    // Main Method
    public static void Main()
    {
  
        // Declaring the decimal variable
        Decimal a = 4.01m;
  
        // finding the floor of the Decimal value
        // using floor() method;
        Decimal value = Decimal.Floor(a);
  
        // Display the Floor
        Console.WriteLine("Floor Value is : {0}",
                                          value);
    }
}
