IBM mainframes use radix 16. This is not likely to change so long as there are IBM mainframes (which will be quite some time). Modern IBM mainframes support radix 2 as an option, but I suspect radix 16 is still the normal default, for historical reasons. So, for example, in SAS C you'll find "#define FLT_RADIX 16". I know of one radix-10 C host: tigcc, a GCC variant for Texas Instrument calculators. It's actively maintained: the latest release was in October. <http://tigcc.ticalc.org/>. This one is more of a curiosity, though. Radix-10 floating point is making a bit of a comeback, by the way. Usually, though, it's not via redefining 'double'. See, for example, <http://www2.hursley.ibm.com/decimal/>.
