Converting

Widening conversion - This is one in which the conversion is to a data type that can accommodate every possible value.
A widening conversion can be implicit or explicit.


Narrowing conversion - This is one in which the conversion is to a data type that does not accommodate every possible value
A narrowing conversion is always explicit.
The following line will not compile

Dim myInteger As Integer 
   myInteger = myDouble

You must use

   myInteger = Ctype(myDouble, Integer)
