Math class in C#
In C#, the Math class is a part of the .NET Framework’s standard library and provides a wide range of mathematical methods and constants for performing common mathematical operations. It is a static class, which means you don’t need to create an instance of it; you can access its methods and properties directly.
Key Features of the Math Class:
1. Static Methods: The Math class comprises static methods for executing mathematical operations like trigonometric functions, exponentiation, logarithms, and more.
2. Mathematical Constants: It provides essential mathematical constants such as π (pi) and the base of the natural logarithm.
Common Methods of the Math Class:
Rounding and Absolute Value: Utilize methods like Math.Round(), Math.Floor(), and Math.Abs() for rounding numbers and obtaining absolute values.
Math.Round() is used to round a numeric value to the nearest integer.
Math.Floor() is used to round a numeric value down to the nearest integer less than or equal to the given value.
Math.Abs() is used to obtain the absolute value of a numeric expression, which is its positive magnitude.
Square Root: Calculate square roots using Math.Sqrt().
Min and Max Values: Find the minimum and maximum of two values using Math.Min() and Math.Max().
The Math.Truncate() method in C# is used to remove the decimal part of a number, effectively rounding toward zero. It returns an integral part of the specified number as a double.
The Math.Pow() method in C# is used to calculate a specified number raised to the power of another specified number.
Examples of Common Methods:
// Math.Floor(): Rounds a number down to the nearest integer.
double weight = 10.75;
double floorWeight = Math.Floor(weight);
Console.WriteLine(floorWeight); // floorWeight is 10
// Math.Max(): Returns the larger of two numbers let’s take a set of 2 numbers (40, 60).
int greatermarks = Math.Max(40,60) // check the greater one
Console.WriteLine(greatermarks); // greatearmarks is 60
// Math.Min(): Returns the smaller of two numbers let’s take a set of 2 numbers (40, 60).
int smallermarks = Math.Min(40,60) // check the smaller one
Console.WriteLine(smallermarks); // smallermarks is 40
//Math.Sqrt(): Calculates the square root of a number.
double Area = 64;
double SqArea = Math.Sqrt(Area); // 8 x 8 = 64
Console.WriteLine(SqArea); // SqArea is 8
//Math.Abs(): Returns the absolute (non-negative) value of a number.
double temperature = Math.Abs(-5.2); // it converts negative value to positive
Console.WriteLine(temperature); //temperature is 5.2
//Math.Round(): Rounds a number to the nearest integer.
double height = Math.Round(7.6); // if height is less than 7.5 answer will be 7 otherwise height will be 8
Console.WriteLine(height); //rounded number is 8
//Math.Pow(): Raises a number to a specified power.
double result = Math.Pow(2.0, 3.0); // double result = 2 x 2 x 2 = 8;
Console.WriteLine(result); //result is 8
//Math.Truncate(): Removes the decimal part of a number (rounds to zero).
double amount = Math.Truncate(100000.897);
Console.WriteLine(amount); //amount is 100000

The Math class in C# is a built-in class in the System namespace that provides static methods for performing mathematical operations such as trigonometry, logarithms, rounding, and more.
No, the Math class is part of the System namespace, which is included by default in C# projects.
Popular methods include Math.Abs() (absolute value), Math.Pow() (power), Math.Sqrt() (square root), Math.Round() (rounding), Math.Max() (maximum), and Math.Min() (minimum).
Use the Math.Round() method:
double roundedValue =
Math.Round(4.5);//output: 5
