try in this way:

B4X:

''''''''''''''''''''''''''''''''
dim a as int
dim b as string
b="10"
a=b
''''''''''''''''''''''''''''''''''
'in this case a=10 (in integer format!)
'or
''''''''''''''''''''''''''''''''
dim a as int
dim b as string
a=10
b=a
'in this other case b="10" (in string format!)
''''''''''''''''''''''''''''''''''

so if an integer value is putted into a string var, it became a string, in implicit conversion.
and someone correct me if I'm wrong!
bye!

Ok, thanks.

Seems to work that it "automatically" converts to a string

Cheers,

When converting a number to a string you are advised to use NumberFormat (or NumberFormat2), as you can get some odd results otherwise. Erel has explained it but I cannot find the reference.

Also IsNumber is useful to check that a string is valid as a number before trying to convert it.

Actually the automatic conversion should work properly with or without NumberFormat.

OK, I just seem to remember reading something on here (or was that for long values?).
