One of those odd things I learned the hard way is that if you are writing a shared object (library/.so) and any programs that will link to that library uses floating point numbers, the library must be compiled as if it uses floating point numbers. What that really means is,...

The Fortran 95 compiler,f95, provides an include file,system.inc,that defines the interfaces for most non-intrinsic library routines. Include this file to insure that functions you call and their arguments are properly typed, especially when default data types are changed with-xtypemap. include '...
Next attempt to read returns CONTROL-D For any logical unit, do not mix normal Fortran input with getc(). 1.4.16.2 fgetc: Get Next Character From Specified Logical Unit The function is called by: INTEGER*4 fgetc status = fgetc( lunit, char ) lunit INTEGER*4 char character Return value ...
Therefore, having a bitwise reproducible answer (even if only during testing) is important if only to understand when the answer could have changed. The issue largely comes in regarding floating point mathematical operations that can occur in a non-deterministic order, since floating point arithmetic...
But in addition, at the very first statement after this callI can see that a couplevariables have "lost" their previously computed value. The program will continue but will give wrong results. I suspect that my floating point stack is getting corrupted. So when I add /Qfpstkchk option, I...
Also, the floating point exception handling features and the intrinsic ieee_exceptions module introduced in F2003 may be useful if you want to hunt down this issue. Translate 0 Kudos Copy link Reply Guillaume_De_Nayer Beginner 08-24-2014 11:56 PM 1,948 Views Hi, During the week...
Prior to this change, an end of file during read was generated when this condition was encountered. Also, prior to this change, the switch /fpscomp=general would allow the last record to not contain a record terminator. The BUFFERED= keyword has been added to the OPEN and INQUIRE ...
Floating point literals can be declared with a specific kind using a suffix 1.23456e78_real_kind The exact value of real_kind is not standardized and differs from compiler to compiler. To inquire the kind of any real variable or constant, the function kind() can be used: print *, kind(...
Let me just point out that I gave you some bad information. The simulation is running on a Windows 8 machine and I was unfamiliar with the "new" task manager. According to what I am now reading, I am seeing memory being eaten at nearly 100% by the app, but CPU...
