What you mean by "tan inverse of a value" ?

The best one for you to use is if you use the values as a float, it's probably what you will come across most though there are others for double's and long doubles. BTW, it is referred to as an arc tangant rather than an inverse tangant in programming. It can be called that in math as well but it is generally referred to as inverse. Just for reference, so you can find the fuction definitions on the net when you need to in future.

float angle = atanf(value);

I think there is no tan inverse in Poland!

Yep, that's true. We don't talk about functions inverse for sin, cos and tan only arc functions. That's where my confusion came from
