Values of type
Rational
represent rational numbers exactly as the ratio of two
Integer
s. Applying
toRational
to an
Integral
number
n
will produce the rational number
n % 1
; applying
toRational
to a
Real
number will produce its rational value (or its closest approximation). One can also construct
Rational
values explicitly using the
(%)
operator. For example, the fraction 2/3 is constructed using
2 % 3
.
