PyQt6 QDoubleSpinBox Error

PyQt6 QDoubleSpinBox Error was created by JT
Just a heads up for anyone writing their own GUI using PyQt. Tom on the IRC discovered that if you set singleStep(0.1) and have minimum to a negative number and using the arrow to go down until you get a large number from value() then go up to -0.0 the value is a huge exponent number. So what I did was use the Python f string to limit the decimals and that fixed the issue for me.

Hi,
That number is quite normal to see in c or c++. And indeed using a limit on the decimals shows 0.0000
We often call this kind of number expressions : "scientific notations".
1e-6 is a common notation used by me to verify if something is close to zero.
In c++ we use std::fixed to get rid of scientific notations. Python uses
