Comments:

C - Simple, clean and fast

C++ - Unlike C, C++ version does bounds checking, otherwise performaces are mostly the same

Nim - Uses Quake square root algorithm

Delphi2010 - Uses old 32 bit compiler

Node/V8 - It's blazing fast keeping in mind that it has to make sense out of javascript

PHP7 - For interpreted language (without JIT) this is close to what is possible to get

Fortran - Finally completed fortran port, it was much easier then expected

Tested On

All tests are done on AMD FX-8120 cpu.
