chore: fix architecture dependent results in tests

Now we return the converted value with error, we can face issues
when the architecture provides different results for the same input.

For example, -1.0 as uint64 is 18446744073709551615 on Linux/amd64,
but 0 on Darwin/arm64.

Same for -1 to uint that is 18446744073709551615 on Linux/amd64,
but -18446744073709551615 on Darwin/arm64.

For this reason, we removed the converted value from the examples that
fails depending on the architecture.
