Step 1: Click Visual Basic to Cut-n-paste code into clsCShort.vb
Public Class clsCShort Public Sub Main() '***************************************************************************************** ' Purpose: Converts positive and negative numbers into Short data type ' ' Syntax: CShort(expression) ' ' Parameter1: expression - -32,768 through 32,767; fractional parts are rounded ' ' Result: Short - signed 16-bit (2-byte) integers ' ' '**************************************************************************************** ' This example is from http://idealprogrammer.com Console.WriteLine("Example #1: CShort(expression)") Dim Short1 As Short = CShort(1.33) Console.WriteLine(Short1) ' Returns 1 'write blank line to make output easier to read Console.WriteLine() Console.WriteLine("Example #2: CShort(expression)") Dim Short2 As Short = CShort(-3.4) Console.WriteLine(Short2) ' Returns -3 'write blank line to make output easier to read Console.WriteLine() Console.WriteLine("Example #3: CShort(expression)") Dim Short3 As Short = CShort(5.5) Console.WriteLine(CShort(Short3)) ' Returns 6 'Prevent console from closing before you press enter Console.ReadLine() End Sub End Class |
Step 2: Click Visual Basic to Cut-n-paste code into Module1.vb
Module Module1 Sub Main() Dim myclsCShort As New clsCShort myclsCShort.Main() End Sub End Module |
