It is when you say 'random'. D's fp math is not random, it is completely 
deterministic, and I've told you so before. You've been pushing the 'random' 
notion here, and other people have picked it up and inferred they'd get random 
results every time they ran a D compiled program.

Please use correct meanings of words.
