Heh. They are displayed. But the rounding is wrong for them, so -1 is
rounded to 0.
We use "(int)(val+0.5)" which works fine for positive values, but for
negative values integer truncation truncates towards zero. So -1+0.5
is -0.5, and then truncates to 0.
This should fix things, and prints things out more nicely anyway if
you happen to have fractional degrees.
