[Gambas-user] Numeric operation between strings.

[user]

ok i see this but

CStr(-19776) output is it a string?

for example i think there is difference between

DIM sVar1="-19776" AS String
DIM iVar2=-19776 AS Integer

why Gambas re-convert a string to integer again when see a + operator?

The statement
PRINT CStr(-19776) + CStr(-19776)

should be equal to

PRINT ("-19776" + "-19776")

and raise an error, strings cannot be sumed.

This function of Gambas seems to reconvert strings to numbers with +
operator.

Should be this happend?
