Question

how can i define a function which can do float divide when i input int

Answer 1

An int will be upcast to a float automatically. The problem that you may notice is a lack of precision if you're returning a float to an int variable.

Answer 2

@eSpeX but it still doesnot work can u give me a example code?

Answer 3

In which language? Some are dynamically typed and some are not. If the language is not dynamically typed, you will need to change it to a float.

Answer 4

The question now becomes, "What doesn't work?"
An example of the code you are using will go a long way to helping others debug it.
