[Scilab-users] Confusion about types (typeof vs. Variabe Browser)

[Federico Miyara]

Dear all,

Regarding the question I've sent a few days earlier (see below), I think 
the Variable Browser in some cases may be creating confusion between 
variable types and number formats

For instance,

a = 1.22

creates a variable of type "constant", while its format is "double".

Regards,

Federico Miyara
