Utilizing Built-in Math Class Functions in Visual Studio for Effective Programming

This resource guides programmers in applying built-in Math class functions available in Visual Studio, focusing on key functions such as Absolute Value (Abs), Square Root (Sqrt), Sign, and Rounding (Round). Each function is explained with its purpose and functionality across various data types such as Decimal, Double, and Int32. The tutorial includes a practical project where users will create an application called "mathExample" to demonstrate these functions. With step-by-step instructions, programmers can easily implement these essential math functions in their applications.

  3. Math Class Functions • Visual Studio provides the programmer with multiple built-in functions from the Math class, including the following: • Math Class Functions • Absolute Value (Abs) • Square Root (Sqrt) • Sign (Sign) • Rounding (Round) • The Math class is not limited to just these four functions.

  4. Math Class Functions • The Math class provides programmers with numerous functions. • We will only look at a few of these functions. • Abs(num) • Returns the absolute value of a positive or negative number • Sqrt(num) • Returns the square root of a number • Sign(num) • Returns the sign of a number • Round (num, places) • Returns number nearest to the specified value.

  5. Using Abs(num) • The Abs() function works with the following data types: • Decimal, Double, Int16, Int32, Int64, SByte, Single

  6. Using Sqrt(num) • Returns the square root of a number as a double

  7. Using Sign(num) • The Sign() function works with the following data types: • Decimal, Double, Int16, Int32, Int64, SByte, Single

  8. Round Function • The Round() function works with either a decimal or a double. The variable/value that represents the number of places should be an Integer. Note that .5 does round up here.

  9. Try It! • Create a new application called mathExample • Save it into the location as instructed by your teacher. • Add the following controls. • When the button is clicked, the appropriate answer should be displayed in the lblAnswer label. • When the btnRound is clicked, it should display an input box to ask for the number of decimal places.
