as_integer_ratio docstring's

[skirpichev]

For builtin/stdlib types we have

int:

    Return integer ratio.

    Return a pair of integers, whose ratio is exactly equal to the original int
    and with a positive denominator.

Fraction:

as_integer_ratio(self)
    Return the integer ratio as a tuple.

    Return a tuple of two integers, whose ratio is equal to the
    Fraction and with a positive denominator.

float:

    Return integer ratio.

    Return a pair of integers, whose ratio is exactly equal to the original float
    and with a positive denominator.

Decimal:

    Return a pair of integers, whose ratio is exactly equal to the original
    Decimal and with a positive denominator. The ratio is in lowest terms.
    Raise OverflowError on infinities and a ValueError on NaNs.

All methods actually return a pair, whose ratio is in lowest terms, but only the last docstring says this explicitly. Shouldn't other methods do same? (Taken from this.)

Edit: Ditto for some sphinx docs, e.g. for the float.as_integer_ratio(): "Return a pair of integers whose ratio is exactly equal to the original float and with a positive denominator. Raises OverflowError on infinities and a ValueError on NaNs."
