It looks like DiscretizeRegion struggles with some circular arcs, in a way that seems to depend on the data types of the chosen angles. An angle specification of {0, 2} (integers) gives the correct result (left), but {0, 2.} does not (right). Can anyone confirm and/or explain? I'm running 10.3.0.0 on 64-bit Windows.

GraphicsRow[DiscretizeRegion[Circle[{0, 0}, 1, #]] & /@ {{0, 2}, {0, 2.}}]

Two discretizations of the same circular arc

This appears to be fixed in v11, at least.

GraphicsRow[DiscretizeRegion[Circle[{0, 0}, 1, #]] & /@ {{0, 2}, {0, 2.}}]
