 These functions differ slightly from the C standard library *by design* - **to stay fast, they don't do range checking or follow C's precision requirements.** Think of these routines more as "decent approximations", for when you know the particular input domain and you have leeway with the output. Video games are a good example of an appropriate use case.
 
 # API
-These functions stick to the C API, but it doesn't implement all of `math.h` - notable exclusions are machine-related functions (e.g. `fma`, `nextafter`), precision-related functions (e.g. `expm1`), complex numbers, and `tgamma`/`lgamma`. But you've got your standard elementary functions and hyperbolic trig as well.

 # Exceptions to branch-free rule
-`atan2` likely compiles to branches; it's hopelessly discontinuous.
-`dtoa` is a crappy implementation, included for completion.

+- An implementation of `dtoa` is included, but like all of the functions, it should only be treated as an approximation.
 
 # Credits
 **There are no credits.** I want this library to be easy to use - which means public domain, and no attribution necessary.
