-From: Maxim Cournoyer <maxim.cournoyer@gmail.com>
-Date: Wed, 17 Jun 2020 23:20:53 -0400
-Subject: [PATCH] tests: Fix tests on non-x86_64 platforms.
-
-On platform other than x86_64 such as aarch64-linux or i686-linux,
-some double comparisons would fail.
-
-See <http://issues.guix.gnu.org/41827>.
-
-* tests/bezier-test.cpp: (Casteljau): Replace EXPECT_EQ by
-EXPECT_near.
-(Subdivide): Replace EXPECT_EQ by EXPECT_DOUBLE_EQ.
-(Portion): Replace EXPECT_EQ by EXPECT_near.
-* tests/ellipse-test.cpp (BezierIntersection): Lower error tolerance
-from 6e-13 to 6e-12.
-(LineIntersection): Replace EXPECT_DOUBLE_EQ by EXPECT_NEAR.
-* tests/line-test.cpp (Reflection): Replace EXPECT_FLOAT_EQ BY
-EXPECT_near.
-(Coefficients): Skip test.
-* tests/parallelogram-test.cpp (area): Replace EXPECT_EQ by
-EXPECT_DOUBLE_EQ.
