Comment:

 Closing for want of a test case: I also believe this to be by design, for
 example:

 ibeta_inv(200.0, 300.0, float_prior(1.0))

 yields ~0.58, but while this is a long way from 1, it is also correct.
 Basically ibeta is so sensitive in some areas, that if p is very close to
 but not 1, then the result really should be != 1.
