Then I suggest we make it an option. I've used single precision
results for almost all my simulations, and I don't think I've
ever found it a problem. It's easy enough to make it a flag
on the .options line, and to put a field in the file header
stating which data format it contains.

I didn't think I'd get away with single precision data ;-)
