[boost] Safe to combine boost asinh and boost interval?

Hi,

>From what I can make out of their respective implementations, the interval
library assumes that asinh (when it exists) produces values consistent with
the floating point rounding mode (i.e. rounding up or down as requested).
The boost implementation of asinh doesn't seem to take account of the
rounding mode like this [for x < 0 it returns -asinh(-x), which will be
rounded the wrong way].  Does this mean that the inclusion guarantee is
violated when combining boost interval and boost asinh?

Thanks,
