Description
Summary
Our build fails for s390x because the numbers are not rounded enough:
tests/gtests/internals/test_bfloat16.cpp:79: Failure
[18667s] Expected: (float {expect_bf16}) > (float {initial_value_bf16}), actual: 0 vs 4.59163e-41
Version
3.6
Environment
oneDNN includes hardware-specific optimizations and may behave
differently on depending on the compiler and build environment. Include
the following information to help reproduce the issue:

Observed behavior
Failed build on openSUSE for s390x because of missing rounding.
Expected behavior
Successful build on s390x without test failures.
