> gda_value_stringify(value)

assume that i know, the value return is string, then i can simply use
this function so i can print
(GValue to gchar) the string.  but there is no function to conver
GValue to gint or gfloat..
the only function i can think of is gda_value_numeric but it doesn't do that.

so assume that i know, that i have a double datatypes inside my table
column, how i can get
the value and assign it in a gdouble variable ?

for example, if gchar,

i can simply
gchar *str;
str = gda_value_stringfy ();

thanks..
