String and Math Functions in Visual Basic .NET
In this article, I will explain you about String and Math Functions in Visual Basic .NET.
String Functions
In Visual Basic .NET String data type are supported by the System.String class. The String Classrepresents character strings. When we want to represent a series of characters then we use String data type. String type represents a string of unicode characters and can have up to 2 billion unicode characters. String class have many built-in functions. The String class is a sealed class you cannot inherit another class from the String class. The following code show you some String Functions:
Example:
Imports System.Console
Module Module1
Sub Main()
Dim str1 As String = "My name is Atul Chaudhary"
Dim str2 As String
Dim str3 As String
Dim str4 As String
Dim str5 As String
Dim str6 As String
str2 = UCase(str1)
'converts string to uppercase
WriteLine(str2)
str3 = LCase(str1)
'converts string to lowercase
WriteLine(str3)
str4 = str1.Substring(11, 6)
'returns a substring
WriteLine(str4)
str5 = str1.Clone
'clones a string
WriteLine(str5)
str6 = str1.GetHashCode
'gets the hashcode
WriteLine(str6)
Read()
End Sub
End Module
Output of String Functions:
Math Functions
Visual Studio .NET provides an easy way of performing mathematical calculations. Math functions are stored in System.Math namespace. We have to import this namespace when we want to work with Math functions. Math class have built-in functions which help us calculate the addition, subtraction, multiplication, division, exponentiation, integer division, trigonometry values, square roots, logarithm values, etc. The following code show you some Math Functions:
Example:
Imports System.Console
Imports System.Math
Module Module1
Sub Main()
WriteLine("Tan 90 is" & " " & Tan(90))
'display Tan90 value
WriteLine("Square root of 121 is " & " " & Sqrt(121))
'displays square root of 121
WriteLine("Log value of 15 is" & " " & Log(15))
'displays the logarithm value of 15
Read()
End Sub
End Module
Output of Math Functions:
