I didn't have to have both single and double precision routines present if I managed to mix operations -- as I was want to do; 2. I wouldn't encounter the round-off error that is all too common using single (32-bit) precision; 3. I wouldn't be tempted to "gain a little speed" using single precision and then find, as I often did, that it was *both* slow and lacking in needed precision. I, for one, will be sorry to see it go. Maybe we should work a bit harder and get fast 64-bit hardware -- 32 B I T S I S N O T E N O U G H ! -- Ed Nather ihnp4!{ut-sally,kpno}!utastro!nather Astronomy Dept., U. of Texas, Austin
