[Bug 33059] New: Visual Basic 6 shows overflow error with arithmetic expressions
http://bugs.winehq.org/show_bug.cgi?id=33059 Bug #: 33059 Summary: Visual Basic 6 shows overflow error with arithmetic expressions Product: Wine Version: 1.5.24 Platform: x86 OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown AssignedTo: wine-bugs(a)winehq.org ReportedBy: german_ant_82(a)yahoo.com Classification: Unclassified Regression SHA1: Visual Basic 6 shows overflow errors with arithmetic expressions that has results greather than 32767 When running a program or on the immediate window, Visual Basic 6 shows an overflow error with arithmetic expression that has results greather than 32767. Dim a As Long a = 32768 <-- This doesn't cause any error a = 32767 + 1 <-- This one causes overflow error The error message dialog shows: Run-time error '6': Overflow This is not a normal behavior. Here, the arithmetic expressions are calculated with 16 bits binary numbers with a range from -32768 to 32767, but Visual Basic 6 is a 32 bits environment with integer expressions with a range from -4294967296 to 4294967295. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

CLng and Val does not fix it, really weird but does not seem to be a bug. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

This does work: Dim a as Long a = Clng(32767) + 1 -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.
