Yep, I wrote exactly this but I coudn't make it work on some tests

Still a better love story than Twilight.

In practice, I wouldn't do this
For practice, I did this just to practice some of the builtin tools, because there's not many other ways which require their use.

As I said you in a post above: "Now that you have passed the kata you could look at the other solutions and see how they proceed.".

thanks

as it doesn't truncate nor rounds any numbers

slow_speed = v1 / 3600

Testing : 279 314 77

Rounding 279 / 3600 to 53 significant binary digits here.

@g964 Need a template? Legends say, Landau had one:

Dear Sir/Madam: Your proof of Fermat's Last Theorem has been received. The first mistake is on page [...], line [...]

Parameters are "int" so use only "ints" and no /.

My solution doesn't trunc or round and the fixed tests are the same for all languages that all give the same results.
Now that you have passed the kata you could look at the other solutions and see how they proceed.

For the data you gave the number of seconds is exactly 7920.0 hence 7920 as an int (this result is the same in all languages of the kata).

it is the most accurate and mathematically correct

I am sorry but I strongly doubt of that.
Maybe you should reconsider the way you made the calculations (in particular don't divide by 3600 too soon).

Yeap. Other solutions opened only when I'm done with this task...but it was too late...
Thank's
I'll try to keep in mind pattern matching...Elixir a little bit different for me

Thanks buddy, i will do it
