The real issue here is about rounding to integers, and enums are ints by default, so really the numbers are equivalent to:
Positivo = 0, Negativo = 1, Neutro = 1 Which would make sense by what you see printed out. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of gennady wexler Sent: Saturday, October 16, 2004 10:54 AM To: Iain McCoy; [EMAIL PROTECTED] Cc: mono Subject: Re: [Mono-list] Enum problem On 10/16/04 4:33 AM, "Iain McCoy" <[EMAIL PROTECTED]> wrote: > On Sat, 2004-10-16 at 13:17 +0200, Francis Brosnan Blázquez wrote: >> Hi. >> >> Working with enumerations I've found an strange behaviour.
