CType (Cast to Data Type)
The CType function is used to cast an expression into a specified data type.
Syntax
CType ( Expression, Type )
Example
In the following test program, elements of a String variable array are used in expressions that return different values based on the data type specified with the Ctype function. .
Public Type(6) As String
BeginProg
Type(1) = 3 + "3" + 3 'returns 333
Type(2) = 3 + CType("3",Long) + 3 'returns 9
Type(3) = CType("3",String) + CType(3,String) + "3" 'returns 333
Type(4) = 123456789 + 1.0 'returns 1.234568e8
Type(5) = 123456789 + CType(1.0,Long) 'returns 123456790
Type(6) = 123456789 + CType(1.0,DOUBLE) 'returns 123456790
EndProg
Remarks
This function returns the Expression as the data type specified by the Type parameter.
Parameters
Expression
The Expression parameter is the value or string that should be cast into the specified data type.
Type
Valid data types for the Type parameter are Float Four-byte floating-point data type. Default datalogger data type for Public or Dim variables. Same format as IEEE4. (or IEEE4 Four-byte, floating-point data type. IEEE Standard 754. Same format as Float.), Long Data type used when declaring a variable as an integer., String A data type used when declaring a variable consisting of alphanumeric characters., or
