Because gambas has automatic type conversion. So, if it sees a "+" 
operator, which applies to numbers, it tries to convert its arguments to 
integer (or even float?). I think that this feature, if used with a 
grain of salt, can be very handy. When misused (I am not saying you were 
misusing), it can lead to very surprising results. Use the "&" operator, 
and the result will be no more strange.

Hope it helps, regards,
