The check github.com/gohugoio/hugo/tpl/tplimpl fails on s390x/Fedora Rawhide

[flyn-org]

What version of Hugo are you using (hugo version)?

$ hugo version
0.140.1

Does this issue reproduce with the latest release?

Yes.

The check github.com/gohugoio/hugo/tpl/tplimpl fails on s390x/Fedora Rawhide. I suspect this might be due to floating-point precision. If you search for "1.557407724654" in the following output, you will find it as part of two floating-point outputs. The subsequent digits differ, though.

For math functions that return a float64, maybe we should reduce the precision of the returned value from 16 significant digits to 12 significant digits. Our unit tests for these functions only test for 4 significant digits.

Or, since we already have good unit test coverage on the math functions, skip the tests as defined in tpl/math/init.go.
