In this article we will see how we can get the pixel ratio of the spin box in the floating value, The device pixel ratio is the ratio between physical pixels and logical pixels of the spin box. Common values are 1 for normal-dpi displays and 2 for high-dpi “retina” displays. We can use
devicePixelRatio method to get the pixel ratio but it is not in floating value.
In order to do this we use devicePixelRatioF method
Syntax : spin_box.devicePixelRatioF()
Argument : It takes no argument
Return : It returns float
Below is the implementation
