Bug#649891: how does it work in 64-bit?

[Hans-Christoph Steiner]

Thanks for the bug report and patch, I'm also upstream on this, so I can get it in there.  One question: I noticed that epsilon is 1e-9 as a float.  We're in the process of porting all Pd libraries to support a 64-bit t_float and t_sample.  The 'vbap' library is not there yet, but we hope to get it there.  Does the value of epsilon need to be different when t_float is 64-bit double precision?  Is it possible to make eplison work for both t_float/t_sample as single and double precision?
