Oracle Solaris Studio - Version Forte Developer 6 Update 2 to 12.2 [Release 6.0 to 12]Oracle Solaris on SPARC (32-bit)
Oracle Solaris on SPARC (64-bit)
Oracle Solaris on x86-64 (64-bit)
Oracle Solaris on x86 (32-bit)
Goal
How can Fortran floating point exceptions be trapped on Solaris platforms so that:
0.0 / 0.0 = 0.0
Inf / Inf = Inf
Inf * 0.0 = 0.0
Without trapping all three result in -NaN (Not A Number). Note: "Inf" is infinity.
In Fortran, the default execution of the following sample (test_exceptions.f) will result in :
