But something should be specified. Users should be able to expect 
consistent behavior. Surely there must be some efficiency reason why it 
is not specified (e.g. it uses a low-level C call that is not 
specified)???

I agree with the idea of putting trunc in the math library since it 
seems to similar to floor.
