Double.CompareTo Method in C# with Examples
The Double.CompareTo() method in C# is used to compare this instance to a specified object or Double object and returns an integer that indicates whether the value of this instance is less than, equal to, or greater than the value of the specified object or Double object.
Syntax
The syntax is as follows −
public int CompareTo (double val); public int CompareTo (object val);
Above, the value val in the 1st syntax is a double-precision floating-point number to compare, whereas val for the 2nd syntax is an object to compare.
Example
Let us now see an example −
using System;
public class Demo {
public static void Main() {
double d1 = 150d;
double d2 = 150d;
Console.WriteLine("Double1 Value = "+d1);
Console.WriteLine("Double2 Value = "+d2);
Console.WriteLine("Are both the double values equal? = "+d1.CompareTo(d2));
}
}Output
This will produce the following output −
Double1 Value = 150 Double2 Value = 150 Are both the double values equal? = 0
Example
Let us now see another example −
using System;
public class Demo {
public static void Main() {
double d1 = 20d;
object d2 = 20d;
Console.WriteLine("Double1 Value = "+d1);
Console.WriteLine("Double2 Value = "+d2);
Console.WriteLine("Are both the double values equal? = "+d1.CompareTo(d2));
}
}Output
This will produce the following output −
Double1 Value = 20 Double2 Value = 20 Are both the double values equal? = 0
