Message106297
It's Table 3.6 ("Decimal interchange format parameters") in the final version of IEEE 754; I'm not sure what that corresponds to in the various drafts. It has column headings: "decimal32", "decimal64", "decimal128" and "decimal{k} (k >= 32)".
Parameters for decimal{k}: k must be a multiple of 32. precision is 9*k/32-2. emax is 3*2**(k/16+3). I think these formulas all work for the specific cases k in {32, 64, 128} too, so it should be easy to check that they make sense.
They give an example below the table, too:
"For example, decimal256 would have p = 70 and emax = 1572864." |
