HP49-HP50 : comparison of two "identical Matrixes"

I can't always rely on some conversions as integers less than 2^64 don't always convert nicely to binary (some conversions seem to go through reals or something equivalent.) I cannot sort large integers (bigger than 40 bits) but I just wrote a Heapsort as comparisons work.

Joe Horn's I->B and B->I, available here can do the conversions accurately. LSORT can sort lists of large integers but doesn't work with lists having a mix of exact and approximate numbers. LSORT is also orders of magnitude faster than the built-in SORT.
