Fix testCore: Float comparison for Grid1f tests #431

Closed lukasmerten closed 12 months ago

lukasmerten commented 1 year ago

This PR updates the comparison function to EXPECT_FLOAT_EQ instead of EXPECT_EQ for Grid1f tests. The latter one led to failing test on some architectures.

Thanks to Roark Habegger from UW Madison for finding this bug.
