[Octave-bug-tracker] [bug #49091] MXE Octave 4.20-rc1: test mappers.cc-tst fails

[Rik]

Follow-up Comment #4, bug #49091 (project octave):

The results I am seeing in fntests.log are


***** test
 re = 2.99822295029797;
 im = pi/2;
 assert (acosh (-10i), re - i*im);
!!!!! test failed
ASSERT errors for:  assert (acosh (-10i),re - i * im)

  Location  |  Observed  |  Expected  |  Reason
     ()      2.9982-1.5708i 2.9982-1.5708i   Abs err 6.2172e-015 exceeds tol
0
shared variables 
  scalar structure containing the fields:

    rt2 =  1.4142
    rt3 =  1.7321
***** test
 re = single (2.99822295029797);
 im = single (pi/2);
 assert (acosh (single (10i)), re + i*im, 5*eps ("single"));
 assert (acosh (single (-10i)), re - i*im, 5*eps ("single"));
!!!!! test failed
ASSERT errors for:  assert (acosh (single (-10i)),re - i * im,5 * eps
("single"))

  Location  |  Observed  |  Expected  |  Reason
     ()      2.9982-1.5708i 2.9982-1.5708i   Abs err 7.1526e-006 exceeds tol

When using doubles, it is failing by 31 eps.  When using floats it is failing
by60 eps ("single").  Those are pretty big tolerances.  Do we want to add
those in or disable the library on Windows?
