Scanning Denso QR Bar Code In Visual C# Using Barcode reader for .NET Control to read, scan read, scan image in .NET framework applications. Here is the output from the program: Printing Bar Code In Visual C# Using Barcode maker for Visual Studio .NET Control to generate, create bar code image in .NET applications. Bar Code Recognizer In Visual C# Using Barcode decoder for .NET Control to read, scan read, scan image in Visual Studio .NET applications. Distance to the sun: 5892480000000 inches
Generating Denso QR Bar Code In .NET Framework Using Barcode printer for ASP.NET Control to generate, create Denso QR Bar Code image in ASP.NET applications. Encode QR Code JIS X 0510 In .NET Using Barcode generator for VS .NET Control to generate, create QR Code ISO/IEC18004 image in VS .NET applications. Clearly, the result could not have been held in an int or uint variable The smallest integer types are byte and sbyte The byte type is an unsigned value between 0 and 255 Variables of type byte are especially useful when working with raw binary data, such as a byte stream produced by some device For small signed integers, use sbyte Here is an example that uses a variable of type byte to control a for loop that produces the summation of the number 100 Denso QR Bar Code Encoder In Visual Basic .NET Using Barcode creation for VS .NET Control to generate, create QR Code image in .NET applications. 2D Barcode Generation In C# Using Barcode encoder for VS .NET Control to generate, create Matrix 2D Barcode image in .NET framework applications. Part I: Paint Linear 1D Barcode In C# Using Barcode generation for VS .NET Control to generate, create Linear image in VS .NET applications. Create Code 3 Of 9 In Visual C# Using Barcode generation for .NET Control to generate, create Code 39 image in .NET framework applications. The C# Language
Barcode Drawer In Visual C# Using Barcode drawer for Visual Studio .NET Control to generate, create barcode image in VS .NET applications. Uniform Symbology Specification Codabar Generation In C#.NET Using Barcode generator for .NET framework Control to generate, create ABC Codabar image in VS .NET applications. // Use byte using System; class Use_byte { static void Main() { byte x; int sum; sum = 0; for(x = 1; x <= 100; x++) sum = sum + x; ConsoleWriteLine("Summation of 100 is " + sum); } } Encode Code 128B In ObjectiveC Using Barcode maker for iPhone Control to generate, create Code 128 Code Set C image in iPhone applications. Creating USS Code 128 In Java Using Barcode printer for Java Control to generate, create Code 128C image in Java applications. The output from the program is shown here: Painting UPC Symbol In .NET Framework Using Barcode encoder for Reporting Service Control to generate, create UPC Symbol image in Reporting Service applications. GTIN  12 Encoder In ObjectiveC Using Barcode generation for iPhone Control to generate, create UPCA image in iPhone applications. Summation of 100 is 5050
Paint Data Matrix In None Using Barcode generator for Excel Control to generate, create ECC200 image in Office Excel applications. UPCA Decoder In None Using Barcode reader for Software Control to read, scan read, scan image in Software applications. Since the for loop runs only from 0 to 100, which is well within the range of a byte, there is no need to use a larger type variable to control it When you need an integer that is larger than a byte or sbyte, but smaller than an int or uint, use short or ushort Matrix Barcode Generator In Java Using Barcode printer for Java Control to generate, create 2D Barcode image in Java applications. Making EAN 13 In Java Using Barcode creator for Java Control to generate, create EAN / UCC  13 image in Java applications. FloatingPoint Types
The floatingpoint types can represent numbers that have fractional components There are two kinds of floatingpoint types, float and double, which represent single and doubleprecision numbers, respectively The type float is 32 bits wide and has an approximate range of 15E 45 to 34E+38 The double type is 64 bits wide and has an approximate range of 5E 324 to 17E+308 Of the two, double is the most commonly used One reason for this is that many of the math functions in C# s class library (which is the NET Framework library) use double values For example, the Sqrt( ) method (which is defined by the library class SystemMath) returns a double value that is the square root of its double argument Here, Sqrt( ) is used to compute the radius of a circle given the circle s area: // Find the radius of a circle given its area using System; class FindRadius { static void Main() { Double r; Double area; area = 100; r = MathSqrt(area / 31416); 3: D a t a Ty p e s , L i t e r a l s , a n d Va r i a b l e s
ConsoleWriteLine("Radius is " + r); } } PART I
The output from the program is shown here: Radius is 178412203012729
One other point about the preceding example As mentioned, Sqrt( ) is a member of the Math class Notice how Sqrt( ) is called; it is preceded by the name Math This is similar to the way Console precedes WriteLine( ) Although not all standard methods are called by specifying their class name first, several are, as the next example shows The following program demonstrates several of C# s trigonometric functions, which are also part of C# s math library They also operate on double data The program displays the sine, cosine, and tangent for the angles (measured in radians) from 01 to 10 // Demonstrate MathSin(), MathCos(), and MathTan() using System; class Trigonometry { static void Main() { Double theta; // angle in radians for(theta = 01; theta <= 10; theta = theta + 01) { ConsoleWriteLine("Sine of " + theta + " is " + MathSin(theta)); ConsoleWriteLine("Cosine of " + theta + " is " + MathCos(theta)); ConsoleWriteLine("Tangent of " + theta + " is " + MathTan(theta)); ConsoleWriteLine(); } } } Here is a portion of the program s output: Sine of 01 is 00998334166468282 Cosine of 01 is 0995004165278026 Tangent of 01 is 0100334672085451 Sine of 02 is 0198669330795061 Cosine of 02 is 0980066577841242 Tangent of 02 is 0202710035508673 Sine of 03 is 029552020666134 Cosine of 03 is 0955336489125606 Tangent of 03 is 0309336249609623 To compute the sine, cosine, and tangent, the standard library methods MathSin( ), MathCos( ), and MathTan( ) are used Like MathSqrt( ), the trigonometric methods are called with a double argument, and they return a double result The angles must be specified in radians Part I:
