Is there an easy way to convert `0.005`

to a Rational 1//200 ?

I guess `0.005`

has no exact representation in base 2, which is why it is interpreted as this terribly long fraction.

EDIT: **Actually my use case is more “general” than the above example.**

I have a float which is the result of an Integer division where both arguments have ‘few’ digits (probably less than 6 in general). A better example is `Rational(43/550)`

. I.e. given `0.07818181818181819`

I would like to obtain 43 and 550.

```
julia> a = Rational(1,200); b = Rational(0.005); iszero(float(a)-float(b))
true
julia> a
1//200
julia> b
5764607523034235//1152921504606846976
```
