Struct ordered_float::OrderedFloat

pub struct OrderedFloat<T: Float>(pub T);

A wrapper around Floats providing an implementation of Ord and Hash.

NaN is sorted as greater than all other values and equal to itself, in contradiction with the IEEE standard.

Methods

impl<T: Float> OrderedFloat<T>

pub fn into_inner(self) -> T
