Function malachite_base::num::random::random_primitive_float_range

pub fn random_primitive_float_range<T: PrimitiveFloat>(
    seed: Seed, 
    a: T, 
    b: T
) -> RandomPrimitiveFloatRange<T>

Generates random primitive floats in the half-open interval $[a, b)$.

Every float within the range has an equal probability of being chosen. This does not mean that the distribution approximates a uniform distribution over the reals. For example, if the range is $[0, 2)$, a float in $[1/4, 1/2)$ is as likely to be chosen as a float in $[1, 2)$, since these subranges contain an equal number of floats.

Positive and negative zero are treated as two distinct values, with negative zero being smaller than zero.

NaN is never generated.

$a$ must be less than $b$. This function cannot create a range that includes T::POSITIVE_INFINITY; for that, use random_primitive_float_inclusive_range.

The output length is infinite.

Expected complexity per iteration

Constant time and additional memory.

Panics

Panics if $a \geq b$.
