In this article we will see how we can get the pixel ratio scale for the spin box. The device pixel ratio is the ratio between physical pixels and logical pixels of the spin box. Pixel ratio scale is the type of variable measurement scale which is quantitative in nature. Ratio scale allows any researcher to compare the intervals or differences.
In order to do this we use devicePixelRatioFScale method
Syntax : spin_box.devicePixelRatioFScale()
Argument : It takes no argument
Return : It returns float
Below is the implementation
