() noexcept¶ Creates a new fraction representing 0/1.
-
constexpr
fraction
(long numerator, long denominator) noexcept¶ Creates a new fraction representing
numerator
/denominator
.Parameters: - numerator – the fraction’s numerator
- denominator – the fraction’s denominator
Requires: denominator
is not zero
-
constexpr long
numerator
() const noexcept¶ Returns: the numerator of this fraction
-
constexpr long
denominator
() const noexcept¶ Returns: the denominator of this fraction
-
constexpr double
as_double
() const noexcept¶ Returns: the result of dividing the numerator by the denominator of this fraction, as a double
.
Note
This feature is only available if the
OGONEK_USE_BOOST
macro is set.-
constexpr
fraction
(boost::rational<long> r) noexcept¶ Creates a new fraction from a
boost::rational<long>
.
-
constexpr
operator boost::rational<long>
() const noexcept¶ Returns: a boost::rational<long>
equivalent to this fraction.
