If possible, use values of the same data type, so Visual Basic does not need to do any conversion. Use CType or one of the other conversion keywords so that the conversion is explicit.See AlsoConceptsImplicit and Explicit ConversionsReference...

Non-Ambiguity Rule: An implicit conversion is only inserted if there is no other possible conversion to insert.If the compiler has two options to fixx+y, say using eitherconvert1(x)+yorconvert2(x)+y, then it will report an error and refuse to choose between them. It would be possible ...
