| data Ratio a |
| Rational numbers, with numerator and denominator of some Integral type.
|  Instances | |
|
|
| type Rational = Ratio Integer |
| Arbitrary-precision rational numbers, represented as a ratio of
two Integer values. A rational number may be constructed using
the % operator.
|
|
| (%) :: Integral a => a -> a -> Ratio a |
| Forms the ratio of two integral numbers.
|
|
| numerator :: Integral a => Ratio a -> a |
| Extract the numerator of the ratio in reduced form:
the numerator and denominator have no common factor and the denominator
is positive.
|
|
| denominator :: Integral a => Ratio a -> a |
| Extract the denominator of the ratio in reduced form:
the numerator and denominator have no common factor and the denominator
is positive.
|
|
| approxRational :: RealFrac a => a -> a -> Rational |
approxRational, applied to two real fractional numbers x and epsilon,
returns the simplest rational number within epsilon of x.
A rational number y is said to be simpler than another y' if
Any real interval contains a unique simplest rational;
in particular, note that 0/1 is the simplest rational of all.
