[Qgis-developer] 12 output field types in Field calculator

[Richard Duivenvoorde]

As part of http://hub.qgis.org/issues/14082 I had a look into the Field
Calculator today, and see there are 12 output field types nowadays?

Is there a special reason to do this like this? I understand that eg for
a postgis db it is useful, but from an average user standpoint I think
it is a little too much (besides the already doubled options)?

Or IF there is an apparent use case for this, should we not hide/mask
the corner cases a little?

And (see #14082) make decimal number (real) or text the default type...
by the way) so user X can use the Field calculator without using his/her
brain too much ;-)
And while we are busy with it: also give a big error message when there
is an overflow (like the area calculation in the issue)?
