 I have not checked for performance losses, but if any it should probably be
very small as the overhead is nearly negligeable compared to the rest of the

 I have pending patches that add complete 32 bits support (and the lossy 32 bits
mode).  Support for 32 bits float is also nearly completed (need to be cleaned up).
But I will wait first for the proposed patches to be applied.
