About Rational Number (PEP 239/PEP 240)

<cont.>
The easiest implementation of using fractional datatype is probably to
add a new operator. Some scientific calculators provide a special
operator to signify a fraction (somewhat on the shape of a small L in
mine) and I strongly believe that their internal calculation probably
used fractions even when regular division is used, only when the
calculator have difficulties using fraction (like calculating sin/cos/
tan function) or the screen is not wide enough to represent the
fraction would it use regular division.

Python implemented complex numbers, why not fractions?

Random ramble past here:
Actually, my vision would be not only fractions, but also rooted
number (square root, cube root, etc), it could be possible to
implement a type where a number consist of a rooted number times a
multiplier plus a variable [a + b * root(c, d)]. But I guess this
would be extremely complex and it requires nesting, probably very slow
if implementation isn't good. The advantage of using such is much
faster operations, as long as str() is not called. This actually
reflects my way of doing paper math, I save the lossy operations
(float division, root, trigonometric function) until the very end of
calculation (I'm not fundamentalist though, so compromise sometimes is
done here and there).
