Hi T.Modes, Indeed I just have tested with Hugin 2017.0.0.eac5e8cc546e and it indeed does display fov with thenth degree rounded - and that's very cool ; I was previously on 2014 then 2016 versions. But I'm working with distances equiv. to ~20km , at this distance a simple pixel represents ~ 3.5 meters ; I have to accurate at the hundredth - and I am : I correct my panos multiple time to conform it to my grid ( considering the topographical errors) by a "trial and error" method through the "GL" tab since there's indeed no visible change in this preview window. But when I don't have 360° horizontally I have to guess the hfov considering that there's differences between hugin values and my soft, and thus the pixel/degree ratio. The possibility for me to display the fov to hundredth degree rounded would ease this job - a simple choice of the rounded precision would be welcome :-) . Meanwhile I'll try to recompile and modify as Sean's proposal.
