+# Override defaults for codecov.io checks.
+#
+# Codecov's defaults seem to leave red marks in GitHub CI checks in a
+# rather arbitrary manner, probably because computers are bad with
+# floating point numbers.

+# Allow coverage percentage a precision of zero decimals, and round to
+# the nearest number (for example, 89.957 to to 90; 89.497 to 89%).
+# Coverage above 90% is good, below 80% is bad.
