Struct DistortionScale

#[repr(transparent)]
pub struct DistortionScale(pub u32);

Fixed point arithmetic version of distortion scale

Tuple Fields

0: u32

Implementations

impl DistortionScale

const SHIFT: u32 = 14u32

Bits past the radix point

const BITS: u32 = 28u32

Number of bits used. Determines the max value. 28 bits is quite excessive.

const MAX: u64 = 268_435_455u64

Maximum internal value

pub const fn new(num: u64, den: u64) -> Self

pub fn inv_mean(slice: &[Self]) -> Self

pub const fn blog16(self) -> i16

Binary logarithm in Q11

pub const fn blog64(self) -> i64

Binary logarithm in Q57

pub const fn mul_u64(self, dist: u64) -> u64

Multiply, round and shift Internal implementation, so don’t use multiply trait.
