[][src]Struct rand::distributions::uniform::UniformFloat

pub struct UniformFloat<X> { /* fields omitted */ }

The back-end implementing [UniformSampler] for floating-point types.

Unless you are implementing [UniformSampler] for your own type, this type should not be used directly, use [Uniform] instead.

Implementation notes

Instead of generating a float in the [0, 1) range using Standard, the UniformFloat implementation converts the output of an PRNG itself. This way one or two steps can be optimized out.

The floats are first converted to a value in the [1, 2) interval using a transmute-based method, and then mapped to the expected range with a multiply and addition. Values produced this way have what equals 22 bits of random digits for an f32, and 52 for an f64.
