I would think that finding more than 2 other languages' implementations of =
the same version of the same algorithm would provide a system of voting whi=
ch implementations produce identical outputs for identical inputs.  If your=
 implementation conforms to multiple other implementations on various platf=
orms/ISAs/endianness, then it is likely correct.  If your implementation is=
 the odd man out with multiple of the others producing identical output tha=
t is different than yours, then an opportunity for investigation.
