Saving in single vs double precision has been incorporated as an option in 'File -> Memory
options' for the next EEGLAB release.

I would also concur that staying with double precision is the safest route. I just found in a
colleague's data yesterday that rank(EEG.data) went from 27 (134 channel data) in single precision
to 134 in double precision. In her case, ICA actually failed when data was submitted in single
precision.
