LuaJIT does not handle -0.0 correctly in 'dual number mode' (which is
the default, and only supported mode for LuaJIT arm64). If LuaJIT is
forced to use 'dual number mode' on X64 (where the default is single),
this test will fail in the same manner.
Fix this by using tonumber("-0.0") instead of a -0.0 literal.
