When is a floating point operation ‘invalid’?
It’s obvious that some casts give the ‘wrong’ result, i.e. when you want to store a number that is more than what fits in a variable of a certain type, there is no way to store that value. My question is — why is the status flag of the floating point register set to ‘invalid’? Over/underflow and/or inexact I could live with, by why ‘invalid’? I can’t find any definition anywhere of what specific CPU’s consider ‘invalid’ floating point operations. I also can’t find out why, with a mantissa 9 this register is not set (despite the value not fitting and the cast result being 0), but with a mantissa 10 it is flagged. It seems to me that no relevant maximum/minimum is being passed at that threshold. More importantly (to me), is there a way for me to cast in a way so that the floating point register isn’t touched, ever? The reason being that the code I’m working on relies (later on) on the register not being in an ‘invalid’ state, and I can’t reasonably or reliably modify each use of that register flag check. But also just resetting the flag is error-prone (because of assumptions elsewhere, ‘elsewhere’ being code I can’t touch). I’ve been looking at boost::numeric_cast but that doesn’t seem to help any here, unless I’m missing something somewhere? But in general, any help on how ‘invalid’ floating point operations work would be helpful.

- The invalid floating point operation meaning is that you may have outdated drivers.
- Using a troubleshooter for your computer hardware should help you get rid of this error.
Blue Screen of Death errors are one of the most serious errors that you can encounter on Windows 10. These errors cause many problems.
Therefore, today we’re going to show you how to fix INVALID FLOATING POINT STATE errors.
Steps to fix INVALID FLOATING POINT STATE BSoD error
How can I fix the INVALID FLOATING POINT STATE error?
1. Update Windows 10
Windows updates are important for your system stability and safety. Therefore, we strongly advise you to download the latest patches by using Windows Update.
New patches are released frequently. Many of them offer security improvements, new features, and various bug fixes related to both hardware and software. Therefore, be sure that you download them.
2. Download the latest drivers
- Press Windows Key+ X to open Power User Menu, and Select Device Manager from the list.
- When Device Manager opens, locate the driver that you wish to update, right-click it and select Update Driver Software.
- Select Search automatically for updated driver software and let Windows 10 download and install the new driver.
- Repeat these steps for all drivers that you want to update.
Windows 10 requires drivers in order to work with your hardware. If your drivers are outdated or not compatible with Windows 10, you’ll encounter a Blue Screen of Death error such as INVALID FLOATING POINT STATE.
To fix this any many other BSoD errors, it’s important that you update your drivers.
You can do that simply by visiting your hardware manufacturer’s website and downloading the latest drivers for your device. Bear in mind that you might have to update all drivers on your PC to fix this problem.
You can also use Device Manager to update your drivers, but we have to mention that Device Manager doesn’t always download the latest drivers.
So, it’s usually better to search and download the necessary drivers manually. This solution shows you how to download drivers by using Device Manager.
2.1 Update drivers automatically
Searching for drivers on your own can be time-consuming. So, we advise you to use a tool that will do this for you automatically.
Choose a professional driver solution so you won’t have to manually search for your drivers. This software will always keep your operating system updated with the newest drivers available. It does an excellent job when it comes to missing, outdated, and corrupted drivers.
It uses a large driver database and is able to find the exact driver version you need. This will remove the risk of major issues that may occur when you install faulty drivers.
Outbyte Driver Updater is easy to use. Just let it scan your drivers and repair/update them as you take care of other tasks. You can leave it running in the background as it has a very small footprint.
3. Run the Hardware Troubleshooter
- Open the Settings app and go to the Update & Security section.
- Select Troubleshoot from the menu on the left.
- Select BSOD from the right pane and click Run the troubleshooter.
- Follow the instructions on the screen to complete the troubleshooter.
Another thing we can try is running Windows 10’s built-in troubleshooting tool. This is designed to deal with various system issues, including BSODs.
So, it might be helpful in this case, as well.
Third-party applications can often cause this error to appear, and in order to fix this problem, you need to find and remove the problematic applications.
Your antivirus or firewall can cause this problem, therefore we recommend that you temporarily remove your antivirus program. Uninstalling the antivirus might not fix the problem.
So, it’s recommended you download and use a dedicated removal tool to remove all files associated with your antivirus. Many antivirus companies offer these tools for download, so be sure to use them.
8. Reset Windows 10
- Restart your PC few times during the boot sequence to start Automatic Repair.
- Select Troubleshoot > Reset this PC > Remove everything. Be sure to have Windows 10 installation media ready, because you might need it for this step.
- Select Only the drive where Windows is installed > Just remove my files and click the Reset button.
- Follow the instructions to complete the reset.
After Windows 10 reset is completed, you’ll have a fresh installation of Windows 10 without any third-party applications.
If the INVALID_FLOATING_POINT_STATE error is caused by software, you can fix it easily by performing a Windows 10 reset.
Resetting Windows 10 is fairly simple, and in order to complete it you might need a bootable USB flash drive.
We also have to mention that Windows 10 reset will remove all files from your C partition, so be sure to back up your important files.
If the error appears again, it means that it is caused by your hardware.
9. Check your hardware
Blue Screen of Death errors are often caused by hardware, and if you installed any new hardware recently we suggest that you remove it or replace it.
If new hardware is not the problem, we advise you to check your RAM and all other major hardware components.
INVALID FLOATING POINT STATE BSoD error can be a big problem, but we hope that you managed to fix this error by using our solutions.

What do the error messages «invalid floating point operation», «singular matrix», «diverging parameters» mean?
The model cannot be estimated due to sparse data, a too elaborate model or other reasons. A simpler model should be tried, by removing one or more covariates, covariate categories and/or time points. Often TRIM inidcates the year that causes the model estimation problem. Remove that year from the time-points-selection list, and run the model again. If you were using the time effect model, you have to switch to the linear trend model to be able to do this. Also set the option to automatically delete changepoints that cannot be estimated.
