Conversion Functions 45
converts any data types into a Boolean value.
CDate(Var)
converts any data types into a date value.
You can use these conversion functions to define how OpenOffice.org Basic should perform
these type conversion operations:
Dim A As String
Dim B As Integer
Dim C As Integer
B = 1
C = 1
A = CStr(B + C) ' B and C are added together first, then
' converted to the string "2"
A = CStr(B) + CStr(C) ' B and C are converted into a string,then
' combined to produce the string "11"
During the first addition in the example, OpenOffice.org Basic first adds the integer
variables and then converts the result into a chain of characters. A is assigned the string 2.
In the second instance, the integer variables are first converted into two strings and then
linked with one another by means of the assignment. A is therefore assigned the string 11.
The numerical CSng and CDbl conversion functions also accept decimal numbers. The
symbol defined in the corresponding country-specific settings must be used as the decimal
point symbol. Conversely, the CStr methods use the currently selected country-specific
settings when formatting numbers, dates and time details.
The Val function is different from the Csng, Cdbl and Cstr methods. It converts a string into
a number; however it always expects a period to be used as the decimal point symbol.
Dim A As String
Dim B As Double
A = "2.22"
B = Val(A) ' Is converted correctly regardless of the
' country-specific settings
Checking the Content of Variables
In some instances, the date cannot be converted:
Dim A As String
Dim B As Date
A = "test"
