Struct font_types::F4Dot12

pub struct F4Dot12(/* private fields */);

16-bit signed fixed point number with 12 bits of fraction.

Implementations

impl F4Dot12

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 from_bits(bits: i16) -> Self

Creates a new fixed point value from the underlying bit representation.

pub const fn to_bits(self) -> i16

Returns the underlying bit representation of the value.

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; 2]

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

impl F4Dot12

pub fn from_f32(x: f32) -> Self

Creates a fixed point value from af32.

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

pub fn to_f32(self) -> f32

Returns the value as an f32.

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