Hi All,

As of svn revision 3530 N.nan_to_num no longer works for arrays of complex64. The actual error is raised in the signbit function, but I'm not sure why this is failing. If someone has a quick fix for this that'd be great, if not I'll lodge a full bug report when I get back from lunch :-).

Just noticed that this has already been reported. http://projects.scipy.org/scipy/numpy/ticket/443 Cheers, Tim
