AFAIK, the Croquet project needs to have exactly reproducible float arithmetics on all platforms.
Are you using the exact same code on all platforms for trancendentals and other floating-point functions? If not, that is going to be the greatest source of different results. They tend to vary widely on accuracy, since there is no 1/2 ULP accuracy requirement for those functions, unlike for the defined IEEE operations (+,-,*,/,sqrt)
Yes, Andreas wrote a new plugin to ensure bit-identical floating point ops across platforms.
