Enum Float 

pub enum Float {
    F16,
    F32,
    F64,
    F80,
    F128,
}

A floating point format, named by its width in bits.

The names are the widths because that is what the textual form uses, and a reader who sees f80 should not have to know that it occupies sixteen bytes on the stack. That is a layout question and it belongs to the target, not to the type.

Variants

F16

IEEE binary16, which is _Float16 and __fp16.

F32

IEEE binary32, which is float everywhere we care about.

F64

IEEE binary64, which is double.

F80

The x87 80-bit extended format, which is long double on x86 SysV.

F128

IEEE binary128, which is _Float128, and long double on AArch64 Linux.

Implementations

impl Float

pub const fn bits(self) -> u32

The width of the format in bits.

This is the width of the format and not the size of the object. F80 is eighty bits of format in a ten, twelve or sixteen byte object depending on the target.

pub const fn from_bits(bits: u32) -> Option<Self>

The format of that width, if there is one.

Trait Implementations

impl Ord for Float

fn cmp(&self, other: &Float) -> 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.

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 Float

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Float

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