Struct FixedPoint 

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

A fixed-point decimal.

Implementations

impl FixedPoint

pub const FACTOR: i64 = clap_sys::fixedpoint::CLAP_BEATTIME_FACTOR

The factor by witch to multiply a value in order to make it have the same fixed-point decimal representation as this type.

pub const fn from_bits(bits: i64) -> FixedPoint

Creates a FixedPoint decimal from its internal, raw-byte representation.

pub const fn to_bits(&self) -> i64

Returns the internal, raw-byte representation of this FixedPoint decimal.

pub const fn from_int(val: i64) -> FixedPoint

Creates a FixedPoint decimal from an integer value.

pub const fn to_int(&self) -> i64

Returns the integer part of this FixedPoint decimal, discarding the decimal part.

pub const fn to_float(&self) -> f64

Converts this fixed-point decimal to a floating-point value.

Note that this conversion loses some precision: the FixedPoint decimal has the full 64 bits of precision, whereas f64’s mantissa is only 52 bits wide.

pub fn from_float(val: f64) -> FixedPoint

Converts the given floating-point value to a FixedPoint decimal.

impl Ord for FixedPoint

fn cmp(&self, other: &FixedPoint) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for FixedPoint

fn eq(&self, other: &FixedPoint) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl PartialOrd for FixedPoint

fn partial_cmp(&self, other: &FixedPoint) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool
