At first sight, this seems indeed inconsistent, but I've learned to be wary of "obvious" answers when it comes to Sage's arithmetic.

May I suggest to ask this interesting question on sage-support (or possibly sage-devel) ?

At first sight, this seems indeed inconsistent, but I've learned to be wary of "obvious" answers when it comes to Sage's arithmetic.

The type of the objects may be a hint :

```
sage: type(.45)
<type 'sage.rings.real_mpfr.RealLiteral'>
sage: type(.45/.28)
<type 'sage.rings.real_mpfr.RealNumber'>
```

So `mpfr`

*defines* some operator called `/`

(possibly division) of `RealNumber`

s (and, BTW, of `RealLiteral`

s), ...

```
sage: type(.45%.28)
<type 'sage.rings.real_mpfr.RealNumber'>
```

... as well as something called `%`

(which indeed looks like modulo.

The question is now why `mpfr`

s authors did not define anything called `//`

. And why Sage's developers didn't extend `mpfr`

to define `//`

...

May I suggest to ask this interesting question on sage-support (or possibly sage-devel) ? There might be subtleties I am not aware of.
