A generic, floating-point real.

This trait abstracts the interfaces defined by f16, f32, f64, and f128 so that these may be used as a single type.

The following trait(s) are not required due to some floating-point types not implementing them:

• Display: Not implement by f128
• From<f16>: Not implement by f32
• FromStr: Not implement by f128
• LowerExp: Not implement by f128
• ToString: Not implemented by f128
• UpperExp: Not implement by f128

These trait(s) will be required when standard support arrives.

See also FloatLeast32 and FloatLeast64. See also StdFloat.

Safety

Bits must be an unsigned, integral type of the same width as Self so that transmutations between the two is always valid.

Furthermore, all items must behave exactly as their standard counterparts.

Required Methods

fn from_f16(value: f16) -> Self

Available on crate feature f16 only.

Losslessly constructs a new, floating-point real from an f16 value.

When f32 implements From<f16>, this constructor will be removed.

Note that when f128 stabilises (see #116909), this constructor may be depcreated in favour of from_f128_lossy.

Examples

use multitype::Float;

let v0 = 0.062_500f64 as f32;
let v1 = f32::from_f64_lossy(0.062_500);

assert_eq!(v0.to_bits(), v1.to_bits());

fn from_f128_lossy(value: f128) -> Self

Available on crate feature f128 only.

Examples

use multitype::Float;

let v0 = 0.062_500f128 as f32;

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
