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 comparison 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.
 | 
						|
* 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.
