what causes a floating point exception

A floating point exception has occurred: floating point exception [Overflow]. #1: starlight. Floating point exception: Overflow? Copy link Collaborator Author Bike commented Oct 14, 2016. overflow also seems to do it. Hi! I've activated the Segregated Fluid Temperature Model and I've selected the User-Defined EOS. Posts: 9 Rep Power: 7. I compiled it under VC 2005 using the command line in the comment below. Francesca Guardavaccaro. I've disassembled the executable and found that vector::resize creates a default Point object which is then copied to the new empty elements at the end of the vector. I'm working with a multiphase flow of liquid and vapour heptane. I've tried reducing the skewness, checked the grid, re-entered the boundary conditions (trying to start off with a jet at a very low NPR, without turbulence), no joy.. am I grasping at straws or is it something blindingly obvious? i couldn't trigger an underflow and i don't remember enough about things to get an inexact. Floating-point trap handler operation. A 64-bit floating point number relating to the horizontal velocity of the rocket with respect … I don't know what it's complaining about!. Join Date: Feb 2015.

Shinmera changed the title Floating point exceptions kill Division By Zero Causes a Floating Point Exception (Hard Crash) Oct 14, 2016. So, what exactly happened? New Member . February 1, 2008, 13:29 Re: Floating point exception: Overflow? The IEEE 754 standard defines five exceptions that can occur during a calculation. Fluent keeps coming back with floating point exception, (underflow). Each corresponds to a particular sort of error, such as overflow. To generate a trap, a program must change the execution state of the process using the fp_trap subroutine and enable the exception to be trapped using the fp_enable or fp_enable_all subroutine.. Changing the execution state of the program may slow performance because floating-point trapping causes the process to execute in serial mode. #1: mike Guest . #2: CFD newbie Guest . The floating point number which was converted had a value greater than what could be represented by a 16-bit signed integer. The following program generates a floating point exception in the vector::resize call. I don't know what it's complaining about!. This was probably never noticed due to a bug in GCC x86 where all floating point comparisons do not signal exceptions, however Clang on x86 and GCC on other architectures (including ARM and MIPS) do signal an FP exception here.
