Str
Returns a string representation of a number or Unicode character string
Declare Function Str Overload ( ByVal n As Byte ) As String
Declare Function Str ( ByVal n As UByte ) As String
Declare Function Str ( ByVal n As Short ) As String
Declare Function Str ( ByVal n As UShort ) As String
Declare Function Str ( ByVal n As Integer ) As String
Declare Function Str ( ByVal n As UInteger ) As String
Declare Function Str ( ByVal n As LongInt ) As String
Declare Function Str ( ByVal n As ULongInt ) As String
Declare Function Str ( ByVal n As Single ) As String
Declare Function Str ( ByVal n As Double ) As String
Declare Function Str ( ByRef str As Const String ) As String
Declare Function Str ( ByVal str As Const WString Ptr ) As String
result = Str[$]( number )
number
Str converts numeric variables to their string representation. Used this way it is the String equivalent to WStr applied to numeric variables, and the opposite of the Val function, which converts a string into a number.
Str also converts Unicode character strings to ASCII character strings. Used this way it does the opposite of WStr. If an ASCII character string is given, that string is returned unmodified.

Description
Str converts numeric variables to their string representation. Used this way it is the String equivalent to WStr applied to numeric variables, and the opposite of the Val function, which converts a string into a number.
Str also converts Unicode character strings to ASCII character strings. Used this way it does the opposite of WStr. If an ASCII character string is given, that string is returned unmodified.
Example
Dim a As Integer
Dim b As String
a = 8421
b = Str(a)
Print a, b
Dim b As String
a = 8421
b = Str(a)
Print a, b
Dialect Differences
- In the -lang qb dialect, Str will left pad a positive number with a space.
- The string type suffix "$" is obligatory in the -lang qb dialect.
- The string type suffix "$" is optional in the -lang fblite and -lang fb dialects.
Platform Differences
- DOS version/target of FreeBASIC does not support the wide-character string version of Str.
Differences from QB
- QB does not support the wide-character string version of Str.
