Function malachite_base::num::exhaustive::primitive_floats_increasing

pub fn primitive_floats_increasing<T: PrimitiveFloat>() -> PrimitiveFloatIncreasingRange<T> 

Generates all primitive floats, except NaN, in ascending order.

Positive and negative zero are both included. Negative zero comes first.

NEGATIVE_INFINITY is generated first and INFINITY is generated last. The returned iterator is double-ended, so it may be reversed.

Let $\varphi$ be to_ordered_representation:

The output is $(\varphi^{-1}(k))_{k=0}^{2^{M+1}(2^E-1)+1}$.

The output length is $2^{M+1}(2^E-1)+2$.

• For f32, this is $2^{32}-2^{24}+2$, or 4278190082.
• For f64, this is $2^{64}-2^{53}+2$, or 18437736874454810626.

Complexity per iteration

Constant time and additional memory.
