--- Comment #9 from Peter Bergner <bergner at gcc dot gnu.org> --- (In reply to jos...@codesourcery.com from comment #7) > What are the actual high and low doubles in the return from powl? The > simplest reason for the reported result here would be that powl returns a > result very slightly less than 27 (which is fine; there is no expectation > of powl, or any operations for IBM long double, being correctly rounded). Using gdb, I see: (gdb) info registers f1 f2 f1 27 (raw 0x403b000000000000) f2 -3.0814879110195774e-33 (raw 0xb930000000000000)
