asin returns nan.0

[Alastair Reid]

Are you reporting a bug in Hugs or asking us to debug your code?

If you're reporting a bug in Hugs, it's helpful to pinpoint 
the error and explain why it is an error.

For example, if you said 'print (asin 3.14)' produces 97 but should
produce <whatever the right answer is>, we'd know what to run to
reproduce the bug and we'd know what the bug is.

Or, if you said "print (foo 3.14)" produces 9 and "print (bar 9)"
produces 42 but "print (bar (foo 3.14))" produces 43, we'd know what
your problem was.
