Notes
You can pass a class instance as long as the class implements the Operator Convert method that returns a String.
For real numbers, CStr returns 7 significant digits. When you pass a real number to CStr, the string it returns uses the decimal separator the user specified in system preferences. However, in most cases you will want to use the Format function instead for more precise control of the formatting. Use the Str function if you want to ensure US/English notation.
If you pass a Boolean, CStr will return either the string "True" or "False". If you pass a Color, it will return the hex representation of the color as a String. If you pass a DateTime, it will return the value of the date in SQL Date-time format.
Sample code
This code returns the string representation of two numbers and a Boolean.
Var s As String
Var d As DateTime = DateTime.Now
s = CStr(1) ' returns "1", as a string
s = CStr(d.Day) ' returns the day number as a string
s = CStr(True) ' returns "True"
This code returns the approximation to Pi as a String to 7 significant digits.
Var s As String
Const kPi = 3.14159265358979323846264338327950
s = CStr(kPi) ' returns "3.141593"
