Implementations
sourceimpl FixedI128
impl FixedI128
sourcepub const fn from_inner(inner: i128) -> Self
pub const fn from_inner(inner: i128) -> Self
Create a new instance from the given inner
value.
const
version of FixedPointNumber::from_inner
.
sourcepub const fn into_inner(self) -> i128
pub const fn into_inner(self) -> i128
Return the instance’s inner value.
const
version of FixedPointNumber::into_inner
.
sourcepub const fn from_u32(n: u32) -> Self
pub const fn from_u32(n: u32) -> Self
Creates self from a u32
.
WARNING: This is a const
function designed for convenient use at build time and
will panic on overflow. Ensure that any inputs are sensible.
sourcepub fn from_float(x: f64) -> Self
pub fn from_float(x: f64) -> Self
Convert from a float
value.
sourcepub const fn from_perbill(n: Perbill) -> Self
pub const fn from_perbill(n: Perbill) -> Self
Convert from a Perbill
value.
sourcepub const fn into_perbill(self) -> Perbill
pub const fn into_perbill(self) -> Perbill
Convert into a Perbill
value. Will saturate if above one or below zero.
sourcepub fn try_into_perthing<P: PerThing>(self) -> Result<P, P>
pub fn try_into_perthing<P: PerThing>(self) -> Result<P, P>
Attempt to convert into a PerThing
. This will succeed iff self
is at least zero
and at most one. If it is out of bounds, it will result in an error returning the
clamped value.
sourcepub fn into_clamped_perthing<P: PerThing>(self) -> P
pub fn into_clamped_perthing<P: PerThing>(self) -> P
Attempt to convert into a PerThing
. This will always succeed resulting in a
clamped value if self
is less than zero or greater than one.
sourcepub const fn neg(self) -> Self
pub const fn neg(self) -> Self
Negate the value.
WARNING: This is a const
function designed for convenient use at build time and
will panic on overflow. Ensure that any inputs are sensible.
sourcepub const fn sqrt(self) -> Self
pub const fn sqrt(self) -> Self
Take the square root of a positive value.
WARNING: This is a const
function designed for convenient use at build time and
will panic on overflow. Ensure that any inputs are sensible.
sourcepub const fn try_sqrt(self) -> Option<Self>
pub const fn try_sqrt(self) -> Option<Self>

pub const fn sub(self, rhs: Self) -> Self
Subtract a value and return the result.
WARNING: This is a const
function designed for convenient use at build time and
will panic on overflow. Ensure that any inputs are sensible.
sourcepub const fn mul(self, rhs: Self) -> Self
pub const fn mul(self, rhs: Self) -> Self
Multiply by a value and return the result.
Result will be rounded to the nearest representable value, rounding down if it is equidistant between two neighbours.
WARNING: This is a const
function designed for convenient use at build time and
will panic on overflow. Ensure that any inputs are sensible.
sourcepub const fn div(self, rhs: Self) -> Self
pub const fn div(self, rhs: Self) -> Self
Divide by a value and return the result.
Result will be rounded to the nearest representable value, rounding down if it is equidistant between two neighbours.

function designed for convenient use at build time and
will panic on overflow. Ensure that any inputs are sensible.
sourcepub const fn from_rational(a: u128, b: u128) -> Self
pub const fn from_rational(a: u128, b: u128) -> Self
Calculate an approximation of a rational.
Result will be rounded to the nearest representable value, rounding down if it is equidistant between two neighbours.
WARNING: This is a const
function designed for convenient use at build time and
will panic on overflow. Ensure that any inputs are sensible.
sourcepub const fn from_rational_with_rounding(

Multiply by another value, returning None
in the case of an error.
Result will be rounded to the nearest representable value, rounding down if it is equidistant between two neighbours.
sourcepub const fn const_checked_mul_with_rounding(

rounding: SignedRounding
) -> Option<Self>
Multiply by another value with custom rounding, returning None
in the case of an
error.
Result will be rounded to the nearest representable value, rounding down if it is equidistant between two neighbours.
sourcepub const fn const_checked_div(self, other: Self) -> Option<Self>
pub const fn const_checked_div(self, other: Self) -> Option<Self>
Divide by another value, returning None
in the case of an error.
Result will be rounded to the nearest representable value, rounding down if it is equidistant between two neighbours.
sourcepub const fn checked_rounding_div(
self,
other: Self,
rounding: SignedRounding
) -> Option<Self>
pub const fn checked_rounding_div(
self,
other: Self,
rounding: SignedRounding
) -> Option<Self>
