I inquired:
> How can I use a postfix operation which has optional parameters and specify
> the parameters in the postfix? For example, how can I write N[expr,k]
> as expr // N plus something to express a nondefault value for k ?
and got two answers:
1) Scott.AHill at williams.edu suggested using infix notation, like:
expr~Flatten~1
2) Paul Hinton <paulh at wolfram.com suggested a "pure function" approach:
Pi // N[#,10]&
Thanks to both.
