* ENH: add parameter finder for degrees or freedom
* Add early exit if approximation is precise to machine precision
* Loosen tolerance and add tests in the tails
* Modularize and simplify
* Use overflow error instead of inf
* Relax all test tolerances
* Should use a linter ..
* Relax test tolerance for float precision and remove ill conditioned test with df=1e6
* Fix indentation
* Loosen tolerance for very high degrees of freedom
* Test if approximation is a good hint, otherwise fall back to 0.01
* Add test coverage of all cases for approximation
* Do not use symmetry for better numerical accuracy in the tails
* Add edge case tests
* Exclude float from testing for extreme values
* Update test comment
* Replace non ASCII character..
* Simplify using boost's own relative error function
* Add early exits for df=1 and df=inf
