`pub fn to_bits(self) -> u32`

1.20.0[src]

`pub fn to_bits(self) -> u32`

Raw transmutation to `u32`

.

This is currently identical to `transmute::<f32, u32>(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_ne!((1f32).to_bits(), 1f32 as u32); // to_bits() is not casting! assert_eq!((12.5f32).to_bits(), 0x41480000); Run

`pub fn from_bits(v: u32) -> f32`

1.20.0[src]

`pub fn from_bits(v: u32) -> f32`

Raw transmutation from `u32`

.

This is currently identical to `transmute::<u32, f32>(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 favours 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 signalingness (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.

`pub fn mul_add(self, a: f32, b: f32) -> f32`

[src]

Fused multiply-add. Computes `(self * a) + b`

with only one rounding
error, yielding a more accurate result than an unfused multiply-add.

Using `mul_add`

can be more performant than an unfused multiply-add if
the target architecture has a dedicated `fma`

CPU instruction.

# Examples

use std::f32; let m = 10.0_f32; let x = 4.0_f32; let b = 60.0_f32; // 100.0 let abs_difference = (m.mul_add(x, b) - (m*x + b)).abs(); assert!(abs_difference <= f32::EPSILON);Run

`pub fn div_euc(self, rhs: f32) -> f32`

[src]

`pub fn div_euc(self, rhs: f32) -> f32`

Calculates Euclidean division, the matching method for `mod_euc`

.

This computes the integer `n`

such that
`self = n * rhs + self.mod_euc(rhs)`

.
In other words, the result is `self / rhs`

rounded to the integer `n`

such that `self >= n * rhs`

.

# Examples

#![feature(euclidean_division)] let a: f32 = 7.0; let b = 4.0; assert_eq!(a.div_euc(b), 1.0); // 7.0 > 4.0 * 1.0 assert_eq!((-a).div_euc(b), -2.0); // -7.0 >= 4.0 * -2.0 assert_eq!(a.div_euc(-b), -1.0); // 7.0 >= -4.0 * -1.0 assert_eq!((-a).div_euc(-b), 2.0); // -7.0 >= -4.0 * 2.0Run

`pub fn mod_euc(self, rhs: f32) -> f32`

[src]

`pub fn mod_euc(self, rhs: f32) -> f32`

Calculates the Euclidean modulo (self mod rhs), which is never negative.

In particular, the return value `r`

satisfies `0.0 <= r < rhs.abs()`

in
most cases. However, due to a floating point round-off error it can
result in `r == rhs.abs()`

, violating the mathematical definition, if
`self`

is much smaller than `rhs.abs()`

in magnitude and `self < 0.0`

.
This result is not an element of the function's codomain, but it is the
closest floating point number in the real numbers and thus fulfills the
property `self == self.div_euc(rhs) * rhs + self.mod_euc(rhs)`

approximatively.

# Examples

#![feature(euclidean_division)] let a: f32 = 7.0; let b = 4.0; assert_eq!(a.mod_euc(b), 3.0); assert_eq!((-a).mod_euc(b), 1.0); assert_eq!(a.mod_euc(-b), 3.0); assert_eq!((-a).mod_euc(-b), 1.0); // limitation due to round-off error assert!((-std::f32::EPSILON).mod_euc(3.0) != 0.0);Run

`pub fn powi(self, n: i32) -> f32`

[src]

`pub fn log(self, base: f32) -> f32`

Returns the logarithm of the number with respect to an arbitrary base.

can produce more accurate results for base 2, and
`self.log10()`

can produce more accurate results for base 10.

# Examples

use std::f32; let five = 5.0f32; // log5(5) - 1 == 0 let abs_difference = (five.log(5.0) - 1.0).abs(); assert!(abs_difference <= f32::EPSILON);Run

`pub fn abs_sub(self, other: f32) -> f32`

[src]

`pub fn abs_sub(self, other: f32) -> f32`

: you probably meant `(self - other).abs()`

: this operation is `(self - other).max(0.0)`

in C). If you truly need the positive difference, consider using that expression or the C function `fdimf`

, depending on how you wish to handle NaN (please consider filing an issue describing your use-case too).
