C# Math.FusedMultiplyAdd() – Syntax & Examples

C# Math.FusedMultiplyAdd() – Examples

In this tutorial, we will learn about the C# Math.FusedMultiplyAdd() method, and learn how to use this method to compute the product of two numbers and adding a number to this product, as a single operation, with the help of examples.

FusedMultiplyAdd(Double, Double, Double)

Math.FusedMultiplyAdd(x, y, z) returns the result of (x * y) + z for given x, y and z.

Syntax

The syntax of FusedMultiplyAdd() method is

Math.FusedMultiplyAdd(Double x, Double y, Double z)

where

Parameter	Description
x	First operand for multiplication.
y	Second operand for multiplication.
z	The value that is added to the product of x and y.

Return Value

The method returns result as Double value.

Example 1 – FusedMultiplyAdd(Double, Double, Double)

In this example, we will find the result of (x*y)+z for some combinations of x, y and z, using Math.FusedMultiplyAdd() method.

C# Program

using System;
 
class Example {
    static void Main(string[] args) {
        Double x, y, z, result;

        x = 2;
        y = 3;
        z = 1;
        result = Math.FusedMultiplyAdd(x, y, z);
        Console.WriteLine($"FusedMultiplyAdd({x}, {y}, {z}) = {result}");

        x = 10;
        y = 5;
        z = 3;
        result = Math.FusedMultiplyAdd(x, y, z);
        Console.WriteLine($"FusedMultiplyAdd({x}, {y}, {z}) = {result}");
    }
}

Output

FusedMultiplyAdd(2, 3, 1) = 7
FusedMultiplyAdd(10, 5, 3) = 53

Conclusion

In this C# Tutorial, we have learnt the syntax of C# Math.FusedMultiplyAdd() method, and also learnt how to use this method with the help of C# example programs.
