Using assert_in_delta for floats with extended notation

Ruby
1

Hi all,

For comparing floats I normally do something like this:

assert_in_delta(‘100.324’, ‘100.32’, 0.01)

However, for extended notation it breaks down:

assert_in_delta(1.34341429278853e+15,
18446744073709551616.quo(13731.24), 1.0)

That gives me a failure. What’s the proper way to test this?

Thanks,

Dan

works. (the difference is 1.75)
