In the past, every language has had its own set of keywords for common math operations such
as rounding and trigonometry. In .NET languages, many of these keywords remain. However,
you can also use a centralized Math class that’s part of the .NET Framework. This has the
pleasant side effect of ensuring that the code you use to perform mathematical operations
can easily be translated into equivalent statements in any .NET language with minimal fuss.
To use the math operations, you invoke the methods of the System.Math class. These
methods are static, which means they are always available and ready to use.

The following code shows some sample calculations that you can perform with the Math class:

double myValue;
myValue = Math.Sqrt(81); // myValue = 9.0
myValue = Math.Round(42.889, 2); // myValue = 42.89
myValue = Math.Abs(-10); // myValue = 10.0
myValue = Math.Log(24.212); // myValue = 3.18.. (and so on)
myValue = Math.PI; // myValue = 3.14.. (and so on)


The features of the Math class are too numerous to list here in their entirety. The previous
examples show some common numeric operations.

Do math function in C#.
If I'm off base, please feel free to let me know.

The point is to set right variables type.

double x = 25;
double y = 225;
double result = (x / y)*100;
Response.Write(result.ToString() + "%");


Since simple calculation doesn't need to using math class, you can do it
directly in your code.

Software testing is for the checking the detect faults.
Through the software testing establish confidence in software and evaluate properties of software
Reliability
Performance
Memory Usage
Security
Usability

So the software testing is the very important one work in the project development.
Through which only we provide the very good quality product to clients and satisfies the client needs.

In cegonsoft they provide very good training for the software testing.They provide the training in all the advance tools.
So which the students get the good opportunity in the industry to get placement.

DOTNET
Dot Net is a software-frame work was made by Microsoft Corporation to get rid of the problems of COM, COM+ and DOM which is used to make re-usability of softwares.
In Microsoft view: Dot Net is the Web services strategy to connect information, people, systems, and devices through software.
 Dot Net frame can support many languages.
 It allows interoperability (Each language which is used in the framework can access of other language codes).
 Dot Net provides tools and libraries that enable developers to create Windows software much faster and easier.
 It provides to build, deploy, manage and use connected with quickly manner.
 Also provides secure enhanced solutions with the Web services.
 Dot Net frame work is very easy to use with the intellisense.
 It comprises with the four major Components.
They are:

 Common Language Specification (CLS).
 Framework Class Library (FCL).
 Common Language Runtime (CLR).
 Dot Net Tools.
Main Benefits of the Dot Net are:
It helps to make software better, faster, cheaper, and more secure.

C# is Microsoft's new programming language for the .NET platform.
It combines some of the best features of modern programming languages such as Java, C++ or Visual Basic.
C# is an object-oriented language with single inheritance but multiple interfaces per class.
It supports component-based programming by properties (smart fields), events and delegates (enhanced function pointers).
C# is fully interoperable with other .NET languages such as VB.NET, Eiffel.NET or Oberon.NET.
