Nice thanks for the tip. Was very helpful for me too.

Uphill, both ways, right?

or probably @qavaxb is just making sure that only int, float, complex numbers get multiplied and not others, althought the question doesn't states so.

You care so much about exact value ==' What a man. Remembering my old teacher made me calculates the error epsilon and handled E expression float numbers :<

Well, it's seen, seen again, and seen again again... ;/
It's well built, though, but we have already a lot of this kind of task. Ah just one thing: ALWAYS put fixed tests in the complete test suite, before the random tests.

Not a kata issue. Ask a question about what you don't understand or see the example case.

a man's gotta do what a man's gotta do...

Edit: However, you have got a point. Check out my fork, by inheriting from float the code becomes significantly shorter (while still being equally correct, and tongue-in-cheek).

Best, MFreidank
