Struct png::ScaledFloat

source · [−]

pub struct ScaledFloat(_);

Expand description

An unsigned integer scaled version of a floating point value, equivalent to an integer quotient with fixed denominator (100_000)).

Implementations

source

impl ScaledFloat

source

pub fn in_range(value: f32) -> bool

Gets whether the value is within the clamped range of this type.

source

pub fn exact(value: f32) -> bool

Gets whether the value can be exactly converted in round-trip.

source

pub fn new(value: f32) -> Self

Slightly inaccurate scaling and quantization. Clamps the value into the representable range if it is negative or too large.

source

pub fn from_scaled(val: u32) -> Self

Fully accurate construction from a value scaled as per specification.

source

pub fn into_scaled(self) -> u32

Get the accurate encoded value.

source

pub fn into_value(self) -> f32

Get the unscaled value as a floating point.
