Struct num_rational::Ratio
source · pub struct Ratio<T> { /* private fields */ }
Expand description
Represents the ratio between two numbers.
Implementations§
source§impl<T> Ratio<T>
impl<T> Ratio<T>
These method are const
.
source§impl<T: Clone + Integer> Ratio<T>
impl<T: Clone + Integer> Ratio<T>
sourcepub fn from_integer(t: T) -> Ratio<T>
pub fn from_integer(t: T) -> Ratio<T>
Creates a Ratio
representing the integer t
.
sourcepub fn to_integer(&self) -> T
pub fn to_integer(&self) -> T
Converts to an integer, rounding towards zero.
sourcepub fn is_integer(&self) -> bool
pub fn is_integer(&self) -> bool
Returns true if the rational number is an integer (denominator is 1).
sourcepub fn reduced(&self) -> Ratio<T>
pub fn reduced(&self) -> Ratio<T>
Returns a reduced copy of self.
In general, it is not necessary to use this method, as the only
method of procuring a non-reduced fraction is through new_raw
.
Panics if denom
is zero.
sourcepub fn round(&self) -> Ratio<T>
pub fn round(&self) -> Ratio<T>
Rounds to the nearest integer. Rounds half-way cases away from zero.
