assert that thr formula "sqrt(x) * sqrt(x)" evaluates to "x" in poi
Hi,
we recently updated from apache POI 5.4.1 to 5.5.0 and have experienced a
regression.
We have a test that does something similiar to the following:
expression: sqrt(x) * sqrt(x)
expected value: x
With the old poi version this evaluated as expected, with the new version we
have a difference at x e-12.
Is this intended or a regression? Also see the attachment for a Junit5
reproducer.
Best regards,
Ahmet
