Tim,

At the risk of self promotion, I would suggest TIFF or GeoTIFF.  It is
reasonably widely supported in the geospatial world and should be
sufficient to represent single or double precision floating point data.

Of course there are lots of packages that don't support it too.

I'm not sure that OGC speaks very directly to file formats (other than GML!)
but certainly GeoTIFF is reasonably widely used in OGC services like WCS.

Best regards,
