(j3.2006) Signaling NaN

[Keith Bierman]

http://download.oracle.com/docs/cd/E19205-01/819-5262/aeufh/index.html may
prove to be a useful starting point.

If the question is more "primative" viz. what does PRINT *, 0.0/0.0
produce, the answer on Solaris 11 on an aged x86 box:

khb at opensolaris~>f77 bork.f && a.out
NOTICE: Invoking /opt/SunStudioExpress/bin/f90 -f77 -ftrap=%none bork.f
bork.f:
 MAIN foo:
  -NaN
 Note: IEEE floating-point exception flags raised:
    Invalid Operation;
 See the Numerical Computation Guide, ieee_flags(3M)
khb at opensolaris~>

Please ignore the "opensolaris" that is simply the machine name, I didn't
change it when I upgraded from the last OpenSolaris to Solaris 11.

Oracle is still doing free distribitions, so it's easy to check for oneself
