This article describes about some in built mathematical function of the math class which are useful to perform some operations.
Math functions
Math functions are very useful function when we need to perform mathematical operations such as some trigonometric and logarithmtics. To use these math functions without qualification, import the System.Math namespace.
1. Abs() Function
The Abs Function is used to returns the absolute value of a specified number.
Syntax
Math.Abs(n)
Here, n is the number.
This function returns the absolute value.
2. Min() Function
The Min function is used to find out the minimum value from two number.
Syntax
Math.Min(n1, n2)
Here, n1 and n2 are the two number.
This function returns the min value from n1 and n2.
3. Max() Function
The Min function is used to find out the maximum value from two number.
Syntax
Math.Min(n1, n2)
Here, n1 and n2 are the two number.
This function returns the maximum value from n1 and n2.
4. Sqrt() Function
The pow function is used to returns the square root of the number.
Syntax
Math.Sqrt(n1)
Here, n1 is the number.
This function returns the maximum value from n1 and n2.
This function returns a Double value specifying the square root of a number.
5. Pow() Function
This function is used to Returns a specified number raised to the specified power.
Syntax
Math.Pow(n1, n2 )
Here, n1 is the number and n2 is the power of the number.
6. Sin() Function
This function is used to Returns the sine of the specified angle.
Syntax
Math.Sin(90)
Here, 90 is the angle.
7. Log() Function
This function is used to find the logarithm of a specified number.
Syntax
Math.log(n1)
Here, n1 is the number.
For example
The below example describe all the above function.
Module Module1
Sub Main()
Dim absolute As Integer
absolute = Math.Abs(-16)
Console.WriteLine("The absolute value is: " & absolute)
Dim minimum As Integer
minimum = Math.Min(18, 12)
Console.WriteLine("The minimum value is: " & minimum)
Dim maximum As Integer
maximum = Math.Max(18, 12)
Console.WriteLine("The maximum value is: " & maximum)
Dim square As Integer
square = Math.Sqrt(9)
Console.WriteLine("The square root is: " & square)
Dim power As Integer
power = Math.Pow(2, 3)
Console.WriteLine("The power is: " & power)
Dim sine As Integer
sine = Math.Sin(90)
Console.WriteLine("sine value of 90: " & sine)
Dim logvalue As Integer
logvalue = Math.Log(15)
Console.WriteLine("log value of 16 is: " & logvalue)
End Sub
End Module
