[Octave-bug-tracker] [bug #52243] some integrators don't preserve type single

[Rik]

Follow-up Comment #2, bug #52243 (project octave):

I checked in this cset
(http://hg.savannah.gnu.org/hgweb/octave/rev/5fc5c1a49aa1) which modifies
quadcc to return a single type output if any limit of integration is a single.
 I also changed the function to base the tolerance values on whether the
inputs are double or single.  It is now equivalent to quadgk in using an
AbsTol of 1e-10 for doubles and 1e-6 for singles.

The only quadrature routine which still has a problem is integral3.
