--- Comment #16 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> 2011-04-17 12:39:25 UTC --- I see another rounding issue with this: integer, parameter :: RT=8 print *, 0.09_RT, " RD:" print "(RD,G15.2)", 0.09_RT print "(RD,E15.2)", 0.09_RT print "(RD,D15.2)", 0.09_RT print "(RD,F15.2)", 0.09_RT end Gives: 8.99999999999999967E-002 RD: 0.89E-01 0.90E-01 0.90D-01 0.08 I believe the E and D case should be 0.89E-01 and 0.89E-01
