When using functions from the Universal C runtime (UCRT) on Windows, a test for the complementary error function with single precision floating point values has higher deviations than on other platforms:

***** assert (erfcinv (erfc (single ([-3 -1 -0.4 0.7 1.3 2.8]))),
        single ([-3 -1 -0.4 0.7 1.3 2.8]), -1e-4)
!!!!! test failed
ASSERT errors for:  assert (erfcinv (erfc (single ([-3, -1, -0.4, 0.7, 1.3, 2.8]))),single ([-3, -1, -0.4, 0.7, 1.3, 2.8]),-1e-4)

  Location  |  Observed  |  Expected  |  Reason
    (1)        -2.9994         -3        Rel err 0.00019693 exceeds tol 0.0001 by 0.0001


I'm not sure if there is anything Octave can do about that.

Opening this report so we can tag this as a known issue in the test suite.
