Ah yes, sorry that's a typo as I rushed those examples together.

This is much more like it, good thinking Marius. One block of difference would
explain the magnitude discrepency. And that's the sort of thing I really
want to avoid having to explain in the text. 

Claude also pointed out a possible sign discrepency around zero for
[delta~] which uses IEEE floats instead of t_sample. 
This one is most dangerous if the object is followed by a [wrap~]

Clearly these methods are subtley different and if you're using them in a 
sensitive context the effects are important.

I'm going to stick with your first suggestion of [fexpr~], because it works
well, and you've made me realise it's a useful object to introduce.

cheers,

Andy
