 ## Speed-accuracy trade-off
 
 The 50-bit accurate versions in the `accurate` module are more accurate, but slightly slower, than the 24-bit accurate versions in the `fast` module.
-`fast::lambert_w_0` is around 15% faster than `accurate::lambert_w_0` and `fast::lambert_w_m1` is around 41% faster than `accurate::lambert_w_m1`.
