Struct Scaled 

pub struct Scaled<F> { /* private fields */ }

A product of floats held as m × 2^e, a mantissa m and a whole exponent e kept apart, so that the product never leaves the normal floats however many items it takes. A step leaves the mantissa where it is while its magnitude stays inside 2^±511 (2^±63 in f32), half the floats’ exponents, so that the product of two mantissas stays normal, and moves the mantissa’s exponent into e once it leaves. normal says whether every step so far was a nonzero normal float. ScaledProduct folds into it. The exponent sums exactly up to 2^53 in f64 and 2^24 in f32, which a product that ends inside the floats’ range never nears.

Implementations

impl<F> Scaled<F>

where F: Native,

pub fn value(self) -> F

The float nearest the product: infinite or zero where it lies past the floats’ range, and rounded at most once, where it lies below the normal floats.
