Expand description

This trait provides methods common to all fixed-point numbers.

It can be helpful when writing generic code that makes use of fixed-point numbers. For methods only available on signed fixed-point numbers, use the FixedSigned trait instead, and for methods only available on unsigned fixed-point numbers, use FixedUnsigned.

This trait is sealed and cannot be implemented for more types; it is implemented for FixedI8, FixedI16, FixedI32, FixedI64, FixedI128, FixedU8, FixedU16, FixedU32, FixedU64, and FixedU128.

§Examples

use fixed::{
    traits::Fixed,
    types::{I8F8, I16F16},
};

fn checked_add_twice<F: Fixed>(lhs: F, rhs: F) -> Option<F> {
    lhs.checked_add(rhs)?.checked_add(rhs)
}

let val1 = checked_add_twice(I8F8::from_num(5), Fixed::from_num(1.75));
assert_eq!(val1, Some(Fixed::from_num(8.5)));
// can use with different fixed-point type
let val2 = checked_add_twice(I16F16::from_num(5), Fixed::from_num(1.75));
assert_eq!(val2, Some(Fixed::from_num(8.5)));

The following example fails to compile, since the compiler cannot infer that 500 in the checked_mul_int call is of type F::Bits.

ⓘ
use fixed::traits::Fixed;

fn checked_add_times_500<F: Fixed>(lhs: F, rhs: F) -> Option<F> {
    rhs.checked_mul_int(500)?.checked_add(lhs)
}

One way to fix this is to add a trait bound indicating that any u16 (which can represent 500) can be converted into F::Bits.

use fixed::{traits::Fixed, types::U12F4};

fn checked_add_times_500<F: Fixed>(lhs: F, rhs: F) -> Option<F>
where
    u16: Into<F::Bits>,
{
    rhs.checked_mul_int(500.into())?.checked_add(lhs)
}

let val = checked_add_times_500(U12F4::from_num(0.25), Fixed::from_num(1.5));
assert_eq!(val, Some(Fixed::from_num(750.25)));

While this works in most cases, u16 cannot be converted to i16, even if the value 500 does fit in i16, so that the following example would fail to compile.

ⓘ
use fixed::{traits::Fixed, types::I12F4};

fn checked_add_times_500<F: Fixed>(lhs: F, rhs: F) -> Option<F>
where
    u16: Into<F::Bits>,
{
    rhs.checked_mul_int(500.into())?.checked_add(lhs)
}

// I12F4::Bits is i16, and u16 does not implement Into<i16>
let val = checked_add_times_500(I12F4::from_num(0.25), Fixed::from_num(1.5));

We can use TryFrom to fix this, as we know that F::Bits::try_from(500_u16) will work for both u16 and i16. (The function will always return None when F::Bits is u8 or i8.)

use fixed::{traits::Fixed, types::I12F4};

fn checked_add_times_500<F: Fixed>(lhs: F, rhs: F) -> Option<F>
where
    u16: TryInto<F::Bits>,
{
    rhs.checked_mul_int(500.try_into().ok()?)?.checked_add(lhs)
}

let val = checked_add_times_500(I12F4::from_num(0.25), Fixed::from_num(1.5));
assert_eq!(val, Some(Fixed::from_num(750.25)));

Required Associated Types§

source

type Bits: FixedBits + From<Self::NonZeroBits>

The primitive integer underlying type.

§Examples
use fixed::{traits::Fixed, types::I16F16};
// 32-bit DELTA is 0x0000_0001_i32
const DELTA_BITS: <I16F16 as Fixed>::Bits = I16F16::DELTA.to_bits();
assert_eq!(DELTA_BITS, 1i32);
source

type NonZeroBits: TryFrom<Self::Bits, Error = TryFromIntError>

The non-zero wrapped version of Bits.

§Examples
use fixed::{traits::Fixed, types::I16F16};
let val = I16F16::from_num(31);
let non_zero_5 = <I16F16 as Fixed>::NonZeroBits::new(5).unwrap();
assert_eq!(val % non_zero_5, val % 5);
source

type Bytes

A byte array with the same size as the type.

§Examples
use fixed::{traits::Fixed, types::I16F16};
// 32-bit DELTA is 0x0000_0001_i32
const DELTA_LE_BYTES: <I16F16 as Fixed>::Bytes = I16F16::DELTA.to_le_bytes();
assert_eq!(DELTA_LE_BYTES, 1i32.to_le_bytes());
source

type Frac: Unsigned

The number of fractional bits as a compile-time Unsigned as provided by the typenum crate.

<F as Fixed>::Frac::U32 is equivalent to <F as Fixed>::FRAC_NBITS.

Frac can be used as the generic parameter of fixed-point number types.

§Examples
use fixed::{traits::Fixed, types::extra::U16, FixedI32, FixedI64};
type Fix1 = FixedI32::<U16>;
assert_eq!(Fix1::FRAC_NBITS, 16);
assert_eq!(Fix1::INT_NBITS, 32 - 16);
type Fix2 = FixedI64::<<Fix1 as Fixed>::Frac>;
assert_eq!(Fix2::FRAC_NBITS, 16);
assert_eq!(Fix2::INT_NBITS, 64 - 16);
source

type Signed: FixedSigned

An unsigned fixed-point number type with the same number of integer and fractional bits as Self.

If Self is signed, then Self::Signed is the same as Self.

§Examples
use fixed::{
    traits::Fixed,
    types::{I16F16, U16F16},
};
// I16F16::Signed is I16F16
assert_eq!(<I16F16 as Fixed>::Signed::FRAC_NBITS, I16F16::FRAC_NBITS);
assert_eq!(<I16F16 as Fixed>::Signed::INT_NBITS, I16F16::INT_NBITS);
assert_eq!(<I16F16 as Fixed>::Signed::IS_SIGNED, I16F16::IS_SIGNED);
// U16F16::Signed is I16F16
assert_eq!(<U16F16 as Fixed>::Signed::FRAC_NBITS, I16F16::FRAC_NBITS);
assert_eq!(<U16F16 as Fixed>::Signed::INT_NBITS, I16F16::INT_NBITS);
assert_eq!(<U16F16 as Fixed>::Signed::IS_SIGNED, I16F16::IS_SIGNED);
source

type Unsigned: FixedUnsigned

An unsigned fixed-point number type with the same number of integer and fractional bits as Self.

If Self is unsigned, then Self::Unsigned is the same as Self.

§Examples
use fixed::{
    traits::Fixed,
    types::{I16F16, U16F16},
};
// I16F16::Unsigned is U16F16
assert_eq!(<I16F16 as Fixed>::Unsigned::FRAC_NBITS, U16F16::FRAC_NBITS);
assert_eq!(<I16F16 as Fixed>::Unsigned::INT_NBITS, U16F16::INT_NBITS);
assert_eq!(<I16F16 as Fixed>::Unsigned::IS_SIGNED, U16F16::IS_SIGNED);
// U16F16::Unsigned is U16F16
assert_eq!(<U16F16 as Fixed>::Unsigned::FRAC_NBITS, U16F16::FRAC_NBITS);
assert_eq!(<U16F16 as Fixed>::Unsigned::INT_NBITS, U16F16::INT_NBITS);
assert_eq!(<U16F16 as Fixed>::Unsigned::IS_SIGNED, U16F16::IS_SIGNED);

assert!(u.get_signed_mut().is_none());
source

fn get_unsigned_mut(&mut self) -> Option<&mut Self::Unsigned>

Returns a mutable reference to self as FixedUnsigned if the type is unsigned, or None if it is signed.

§Examples
use fixed::{
    traits::Fixed,
    types::{I16F16, U16F16},
};

let mut u = U16F16::from_num(3.5);
match u.get_unsigned_mut() {
    Some(unsigned) => *unsigned = unsigned.next_power_of_two(),
    None => unreachable!(),
}
assert_eq!(u, 4);

let mut i = I16F16::from_num(3.5);
assert!(i.get_unsigned_mut().is_none());
