# Primitive Type f64
1.0.0[−]

Expand description

A 64-bit floating point type (specifically, the “binary64” type defined in IEEE 754-2008).

This type is very similar to `f32`, but has increased precision by using twice as many bits. Please see the documentation for `f32` or Wikipedia on double precision values for more information.

See also the `std::f64::consts` module.

- Be representable in the return type `Int`, after truncating off its fractional part

1.20.0 (const: unstable)[src]

#### pub fn to_bits(self) -> u64

Raw transmutation to `u64`.

This is currently identical to `transmute::<f64, u64>(self)` on all platforms.

See `from_bits` for some discussion of the portability of this operation (there are almost no issues).

Note that this function is distinct from `as` casting, which attempts to preserve the numeric value, and not the bitwise value.

##### Examples

    assert!((1f64).to_bits() != 1f64 as u64); // to_bits() is not casting!
    assert_eq!((12.5f64).to_bits(), 0x4029000000000000);

Run
1.20.0 (const: unstable)[src]

#### pub fn from_bits(v: u64) -> Self

Raw transmutation from `u64`.

This is currently identical to `transmute::<u64, f64>(v)` on all platforms. It turns out this is incredibly portable, for two reasons:

- Floats and Ints have the same endianness on all supported platforms.
- IEEE-754 very precisely specifies the bit layout of floats.

However there is one caveat: prior to the 2008 version of IEEE-754, how to interpret the NaN signaling bit wasn’t actually specified. Most platforms (notably x86 and ARM) picked the interpretation that was ultimately standardized in 2008, but some didn’t (notably MIPS). As a result, all signaling NaNs on MIPS are quiet NaNs on x86, and vice-versa.

Rather than trying to preserve signaling-ness cross-platform, this implementation favors preserving the exact bits. This means that any payloads encoded in NaNs will be preserved even if the result of this method is sent over the network from an x86 machine to a MIPS one.

If the results of this method are only manipulated by the same architecture that produced them, then there is no portability concern.

If the input isn’t NaN, then there is no portability concern.

If you don’t care about signaling-ness (very likely), then there is no portability concern.

Note that this function is distinct from `as` casting, which attempts to preserve the numeric value, and not the bitwise value.

##### Examples

    let v = f64::from_bits(0x4029000000000000);
    assert_eq!(v, 12.5);

Run
1.40.0 (const: unstable)[src]

#### pub fn to_be_bytes(self) -> [u8; 8]

    assert_eq!(bytes, [0x40, 0x29, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00]);

Run
1.40.0 (const: unstable)[src]

#### pub fn to_le_bytes(self) -> [u8; 8]

Return the memory representation of this floating point number as a byte array in little-endian byte order.

##### Examples

    let bytes = 12.5f64.to_le_bytes();
    assert_eq!(bytes, [0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x29, 0x40]);

Run
1.40.0 (const: unstable)[src]

#### pub fn to_ne_bytes(self) -> [u8; 8]

Return the memory representation of this floating point number as a byte array in native byte order.

As the target platform’s native endianness is used, portable code should use `to_be_bytes` or `to_le_bytes`, as appropriate, instead.

##### Examples

    let bytes = 12.5f64.to_ne_bytes();
    assert_eq!(
        bytes,
        if cfg!(target_endian = "big") {
            [0x40, 0x29, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00]
        } else {
            [0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x29, 0x40]
        }
    );

Run
1.40.0 (const: unstable)[src]

#### pub fn from_be_bytes(bytes: [u8; 8]) -> Self

    assert_eq!(value, 12.5);

Run
1.40.0 (const: unstable)[src]

#### pub fn from_le_bytes(bytes: [u8; 8]) -> Self

Create a floating point value from its representation as a byte array in little endian.

##### Examples

    let value = f64::from_le_bytes([0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x29, 0x40]);
    assert_eq!(value, 12.5);

Run
1.40.0 (const: unstable)[src]

#### pub fn from_ne_bytes(bytes: [u8; 8]) -> Self

Create a floating point value from its representation as a byte array in native endian.

As the target platform’s native endianness is used, portable code likely wants to use `from_be_bytes` or `from_le_bytes`, as appropriate instead.

##### Examples

    let value = f64::from_ne_bytes(if cfg!(target_endian = "big") {
        [0x40, 0x29, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00]
    } else {
        [0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x29, 0x40]
    });
    assert_eq!(value, 12.5);

Run
[src]

#### pub fn total_cmp(&self, other: &Self) -> Ordering

🔬 This is a nightly-only experimental API. (`total_cmp` #72599)

Returns an ordering between self and other values. Unlike the standard partial comparison between floating point numbers, this comparison always produces an ordering in accordance to the totalOrder predicate as defined in IEEE 754 (2008 revision) floating point standard. The values are ordered in following order:

- Negative quiet NaN
- Negative signaling NaN
- Negative infinity
- Negative numbers
- Negative subnormal numbers
- Negative zero
- Positive zero
- Positive subnormal numbers
- Positive numbers
- Positive infinity
- Positive signaling NaN
- Positive quiet NaN

Note that this function does not always agree with the `PartialOrd` and `PartialEq` implementations of `f64`. In particular, they regard negative and positive zero as equal, while `total_cmp` doesn’t.

##### Example

    #![feature(total_cmp)]
    struct GoodBoy {
        name: String,
        weight: f64,
    }

    let mut bois = vec![
        GoodBoy { name: "Pucci".to_owned(), weight: 0.1 },
        GoodBoy { name: "Woofer".to_owned(), weight: 99.0 },
        GoodBoy { name: "Yapper".to_owned(), weight: 10.0 },
        GoodBoy { name: "Chonk".to_owned(), weight: f64::INFINITY },
        GoodBoy { name: "Abs. Unit".to_owned(), weight: f64::NAN },
        GoodBoy { name: "Floaty".to_owned(), weight: -5.0 },
    ];

    bois.sort_by(|a, b| a.weight.total_cmp(&b.weight));

Run
1.50.0[src]

#### pub fn clamp(self, min: f64, max: f64) -> f64

Restrict a value to a certain interval unless it is NaN.

Returns `max` if `self` is greater than `max`, and `min` if `self` is less than `min`. Otherwise this returns `self`.

Note that this function returns NaN if the initial value was NaN as well.

##### Panics

Panics if `min > max`, `min` is NaN, or `max` is NaN.

##### Examples

    assert!((-3.0f64).clamp(-2.0, 1.0) == -2.0);
    assert!((0.0f64).clamp(-2.0, 1.0) == 0.0);
    assert!((2.0f64).clamp(-2.0, 1.0) == 1.0);
    assert!((f64::NAN).clamp(-2.0, 1.0).is_nan());

### impl Rem<f64> for f64

The remainder from the division of two floats.

The remainder has the same sign as the dividend and is computed as: `x - (x / y).trunc() * y`.

## Examples

    let x: f32 = 50.50;
    let y: f32 = 8.125;
    let remainder = x - (x / y).trunc() * y;

    // The answer to both operations is 1.75
    assert_eq!(x % y, remainder);
