Steps to Reproduce

tox -e pypy3-test-instrumentation-flask-1 -- -ra

Expected Result

pass

Actual Result

fail

Additional context

No response

Would you like to implement a fix?

No

Another try:

>>> round(0.0012783256999966852, 2)
0.0
>>> round(0.007484300999976767, 2)
0.01

The fix would be to use places=1 or delta I guess
