Standard functions on rational numbers
Rational numbers, with numerator and denominator of some
|Integral a => Enum (Ratio a)|
|Eq a => Eq (Ratio a)|
|Integral a => Fractional (Ratio a)|
|(Data a, Integral a) => Data (Ratio a)|
|Integral a => Num (Ratio a)|
|Integral a => Ord (Ratio a)|
|(Integral a, Read a) => Read (Ratio a)|
|Integral a => Real (Ratio a)|
|Integral a => RealFrac (Ratio a)|
|Show a => Show (Ratio a)|
|(Storable a, Integral a) => Storable (Ratio a)|
Forms the ratio of two integral numbers.
Extract the numerator of the ratio in reduced form: the numerator and denominator have no common factor and the denominator is positive.
Extract the denominator of the ratio in reduced form: the numerator and denominator have no common factor and the denominator is positive.
approxRational, applied to two real fractional numbers
epsilon, returns the simplest rational number within
x. A rational number
y is said to be simpler than another
Any real interval contains a unique simplest rational; in particular, note that
0/1 is the simplest rational of all.
