validation="number" may need to divide in float and integer

[Junsang-Mun]

Describe the new feature you'd like

I found a little problem that may causes confusion:

Validating age form by "number" type does not throw an error when a type of age is float.
So I was to open a bug issue for this reason but in my opinion, It might be a better solution if the validation type will be divided into two: float and integer.

This feature is expected to minimize the possibility of unexpected errors or bugs by allowing developers to specify the type of variable they need.

perhaps we could just provide an argument to the number validation rule:

validation="required|number:float"
// or
validation="required|number:integer"

I'll merge a PR with these changes if you want to create one
