Discrepancies between try exact and approximate

[vvs-]

I'm not sure if this was intended or an oversight. The display of a result in try exact and approximate mode is different for calculations with approximate numbers. Try e.g.:

set approximation approximate
pi/2
save v
cos(v*rad)
approximate

It is partly intentional. It is caused by a workaround to avoid cos(pi/2) ≈ 5,4845872E-78 in approximate mode.

That's the reason why I'm asking. This issue is about a possible bug, so if it's intentional the issue should be probably documented and closed. I leave that to your discretion.
