/stipulate it if I judged it
relevant. (It is not. I did not mention COBOL in my post, and floating-point
performance has never been an urgent issue in COBOL, where it is little used,
less used than it should be.)
His view that there are packages invocable from C++ that yield better
performance
For n = 50(10)100 I inverted an identity matrix, a unit upper triangular
matrix, and a unit lower triangular matrix using first HFP and then BFP.
The results, stated as index numbers with BFP=100, are summarized below.
50 60 70 80 90 100n
101 101 100 103 10199I
101

Hi
If soemone has some performance comparsion, on z9 or z10 , between HEX
and binary (IEEE) floating point operations
