Hello Get_A_Grip , I understand that you are having issues with a floating math point when doing a subtraction. Regarding this, what I can
The reason for the floating point error is that in the process of converting decimal to binary, there is no way to put all the decimal parts into the mantissa. Since the conversion may have errors, then simply don’t convert it and use decimal. Do calculations. There is a module in Pyt...
Varients of this question come up a lot. For example, it was recently discussed in this thread:

Your language isn’t broken, it’s doing floating point math. Computers can only natively store integers, so they need some way of representing decimal numbers. This representation is not perfectly accurate. This is why, more often than not,0.1 + 0.2 != 0.3. ...

after meshing my geometry and starting my simulation, I come across the a floating point error, attached below. I tried to trace back the error and I found out that the problem lies within the "InletCO2Concentration" as it says that there is no volume data for my specified region, as se...

A very well-known problem is floating point errors. Floating point numbers have limitations on how accurately a number can be represented. The actual number saved in memory is often rounded to the closest possible value. The accuracy is very high and out of scope for most applications, but ...
