How can I set it in float

How can I float reflection tax like this ??
Or any code to set this
??

Hi, there is not a float type in the contract, so generally speaking, if you want to set 0.2, maybe you can pass 20, and then in the contract it would be 20/100, or you can pass 200, and in the contract it would be 200/1000, so the parameter depends on the what the number it would divide.
