I would like a single precision version of 'interp' in the Numeric Core. (I want such a routine since I'm operating on huge single precision arrays, that I don't want promoted to double precision.)

I've written such a routine, but Paul Dubois and I are discussing the best way of integrating it into the core.

One solution is to simply add a new function 'interpf' to arrayfnsmodule.c .

Another solution is to add a typecode=Float option to interp.

Any opinions on how this single precision version be handled?
