new 7cbee90 Move the data from the CReferenceTest to test resources.
7cbee90 is described below
commit 7cbee90fb91da2182107aee2d3b4ff6b980a9ddf
Author: Alex Herbert <aherb...@apache.org>
AuthorDate: Mon Dec 9 23:17:41 2019 +0000
Move the data from the CReferenceTest to test resources.
There are currently some cases of incorrect computations that are
commented out using a ';' character in the test data:
acos.txt:;0.5 0.0 1.0471975511965979 -0.0
acos.txt:;-0.5 -0.0 2.0943951023931953 0.0
