Double.MinValue Field

Represents the smallest possible value of a Double. This field is constant.

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

public const double MinValue

The value of this constant is negative 1.7976931348623157E+308.

The result of an operation that is less than Double.MinValue is Double.NegativeInfinity. In the following example, Double.NegativeInfinity results from subtraction and multiplication operations when the result is less than Double.MinValue.

using System;

public class Example
{
   public static void Main()
   {
      double result1 = -7.997e307 + -9.985e307;
      Console.WriteLine("{0} (Negative Infinity: {1})", 
                        result1, Double.IsNegativeInfinity(result1));

      double result2 = -1.5935e250 * 7.948e110;
      Console.WriteLine("{0} (Negative Infinity: {1})", 
                        result2, Double.IsNegativeInfinity(result2));
   }
}
// The example displays the following output: 
//    -Infinity (Negative Infinity: True) 
//    -Infinity (Negative Infinity: True)

The following code example illustrates the use of MinValue:

	public class Temperature {
		public static double MinValue {
			get {
				return Double.MinValue;
			}
		}

		public static double MaxValue {
			get {
				return Double.MaxValue;
			}
		}

		// The value holder 
		protected double m_value;

		public double Value {
			get {
				return m_value;
			}
			set {
				m_value = value;
			}
		}

		public double Celsius {
			get {
				return (m_value-32.0)/1.8;
			}
			set {
				m_value = 1.8*value+32.0;
			}
		}
	}
