OK, a mainframe system with a 6 year old compiler - that's enough of a niche market that I don't worry too much about the rounding errors that the code may produce. But I now use formulas based LDBL_DIG instead of LDBL_MANT_DIG, so that the code will work with FLT_RADIX = 16 as well (modulo the mentioned rounding errors). Bruno
