Struct font_types::Fixed

pub struct Fixed(_);

32-bit signed fixed point number with 16 bits of fraction.

Implementations

impl Fixed

pub const MIN: Self = _

Minimum value.

pub const MAX: Self = _

Maximum value.

pub const EPSILON: Self = _

This type’s smallest representable value

pub const ZERO: Self = _

Representation of 0.0.

pub const ONE: Self = _

Representation of 1.0.

pub const fn round(self) -> Self

Returns the nearest integer value.

pub const fn abs(self) -> Self

Returns the absolute value of the number.

pub const fn floor(self) -> Self

Returns the largest integer less than or equal to the number.

pub const fn fract(self) -> Self

Returns the fractional part of the number.

pub fn wrapping_add(self, other: Self) -> Self

Wrapping addition.

pub const fn saturating_add(self, other: Self) -> Self

Saturating addition.

pub const fn wrapping_sub(self, other: Self) -> Self

Wrapping substitution.

pub const fn saturating_sub(self, other: Self) -> Self

Saturating substitution.

pub const fn to_be_bytes(self) -> [u8; 4]

The representation of this number as a big-endian byte array.

impl Fixed

pub fn from_f64(x: f64) -> Self

Creates a fixed point value from af64.

This operation is lossy; the float will be rounded to the nearest representable value.

pub fn to_f64(self) -> f64

Returns the value as an f64.

This operation is lossless: all representable values can be round-tripped.

impl Fixed

pub const fn mul_div(&self, a: Fixed, b: Fixed) -> Fixed

Multiplies self by a and divides the product by b.
