if so many people have passed this kata, then please explain that this kata is about solving rounding errors and not about a Tortoise race.

if it weren't for the rounding issue, this is a great kata, but I'm going to just have to "fail" it and move on, this is infuriating. i can't get it to work in any lang so far.

I'm having the same issue. I calculate a minutes that's 19.99999999 which rounds to 19 and is my only error. I'm not sure how to fix it. Anyone?!

how do you solve the rounding errors?

I had a similar problem on the python kata ...

it is a float precision problem - if you print your values, you will see.
In my opinion the test cases are not well selected for "the fractions of a second won't matter" description

As you can see at the top of the page 731 guys passed the Java kata. I just tried a few solutions and all worked fine.

This thing is broken. Failures are clean but when I actually solve (done it several ways), it times out. It's as if whatever happens after tests pass is breaking.
