Data Type Priority in Dyadic Operation

If data of a different data type are designated in a dyadic operation, operation is normally performed after conversion into higher priority data described below.

Operation Example

Example 1

Dim aaa As Integer
Dim bbb As String
aaa = 100
bbb = "DENSO"
PringDbg aaa + bbb 
'The Integer aaa has higher priority so String bbb is automatically converted into Integer
'bbb cannot be converted into Integer, so an error occurs

Example 2

Dim aaa As Integer
Dim bbb As String
aaa = 100
bbb = "90"
PringDbg aaa + bbb 
'The Integer aaa has higher priority so String bbb is automatically converted into Integer
'190 is output

Example 3

Dim aaa As Position
Dim bbb As String
aaa = P(100, 200, 300)
bbb = "90"
PringDbg bbb + aaa
'The String bbb has higher priority so Position aaa is automatically converted into String
' "90P(100, 200, 300, 0, 0, 0, -1)" is output

Attention

In case of string concatenation operator "& operator;" both sides are compulsorily and automatically converted into string type regardless of the priority.
