I do not know if recent math libraries implement a function similar to what is used in the "Fast inverse square root" method (wikipedia article with code & history), but perhaps this is some benefit to you if you ever have performance issues with the sqrt function. No idea how this measures in performance to anything, though.

 

Cheers!
