Cast a variant to a certain type


Source position: varianth.inc line 377

procedure VarCast(

  var dest: variant;

  const source: variant;

  vartype: LongInt



VarCast converts the variant in Source to the type indicated in VarType and returns the result in dest. The VarType must be one of the predefined VarNNN constants.


If the conversion is not possible because the value cannot be correctly casted, then a run-time error or an exception may occur.
