sourcefn wrapping_div(self, rhs: Self) -> Self
fn wrapping_div(self, rhs: Self) -> Self
Wrapping (modular) division. Computes self / rhs
, wrapping around at
the boundary of the type.
§Signed Integers
The only case where such wrapping can occur is when one divides
MIN / -1
on a signed type (where MIN
is the negative minimal value
for the type); this is equivalent to -MIN
, a positive value that is
too large to represent in the type. In such a case, this function
returns MIN
itself.
§Unsigned Integers
Wrapping (modular) division. Computes self / rhs
. Wrapped division on
unsigned types is just normal division. There’s no way wrapping could
ever happen. This function exists, so that all operations are accounted
for in the wrapping operations.
§Panics
This function will panic if rhs
is 0.
sourcefn wrapping_div_euclid(self, rhs: Self) -> Self
fn wrapping_div_euclid(self, rhs: Self) -> Self
Wrapping Euclidean division. Computes self.div_euclid(rhs)
, wrapping
around at the boundary of the type.
§Signed Types
Wrapping will only occur in MIN / -1
on a signed type (where MIN
is
the negative minimal value for the type). This is equivalent to -MIN
,
a positive value that is too large to represent in the type. In this
case, this method returns MIN
itself.
§Unsigned Types
Wrapped division on unsigned types is just normal division. There’s no
way wrapping could ever happen. This function exists, so that all
operations are accounted for in the wrapping operations. Since, for the
positive integers, all common definitions of division are equal, this is
exactly equal to self.wrapping_div(rhs)
.
§Panics
This function will panic if rhs
is 0.
sourcefn wrapping_rem(self, rhs: Self) -> Self
fn wrapping_rem(self, rhs: Self) -> Self
Wrapping (modular) remainder. Computes self % rhs
, wrapping around at
the boundary of the type.
§Signed Integers
Such wrap-around never actually occurs mathematically; implementation
artifacts make x % y
invalid for MIN / -1
on a signed type (where
MIN
is the negative minimal value). In such a case, this function
returns 0
.
§Unsigned Integers
Wrapped remainder calculation on unsigned types is just the regular remainder calculation. There’s no way wrapping could ever happen. This function exists, so that all operations are accounted for in the wrapping operations.
§Panics
This function will panic if rhs
is 0.
sourcefn wrapping_rem_euclid(self, rhs: Self) -> Self
fn wrapping_rem_euclid(self, rhs: Self) -> Self
Wrapping Euclidean remainder. Computes self.rem_euclid(rhs)
, wrapping
around at the boundary of the type.
§Signed Integers
Wrapping will only occur in MIN % -1
on a signed type (where MIN
is
the negative minimal value for the type). In this case, this method
returns 0.
§Unsigned Integers
Wrapped modulo calculation on unsigned types is just the regular
remainder calculation. There’s no way wrapping could ever happen. This
function exists, so that all operations are accounted for in the
wrapping operations. Since, for the positive integers, all common
definitions of division are equal, this is exactly equal to
self.wrapping_rem(rhs)
.
§Panics
This function will panic if rhs
is 0.
sourcefn wrapping_neg(self) -> Self
fn wrapping_neg(self) -> Self
Wrapping (modular) negation. Computes -self
, wrapping around at the
boundary of the type.
§Signed Integers
The only case where such wrapping can occur is when one negates MIN
on a signed type (where MIN
is the negative minimal value for the
type); this is a positive value that is too large to represent in the
type. In such a case, this function returns MIN
itself.
§Unsigned Integers
Since unsigned types do not have negative equivalents all applications
of this function will wrap (except for -0
). For values smaller than
the corresponding signed type’s maximum the result is the same as
casting the corresponding signed value. Any larger values are equivalent
to MAX + 1 - (val - MAX - 1)
where MAX
is the corresponding signed
type’s maximum.
sourcefn wrapping_shl(self, rhs: u32) -> Self
fn wrapping_shl(self, rhs: u32) -> Self
Panic-free bitwise shift-left; yields self << mask(rhs)
, where mask
removes any high-order bits of rhs
that would cause the shift to
exceed the bit-width of the type.
Note that this is not the same as a rotate-left; the RHS of a wrapping
shift-left is restricted to the range of the type, rather than the bits
shifted out of the LHS being returned to the other end. The primitive
integer types all implement a rotate_left
function, which may be what
you want instead.
sourcefn wrapping_shr(self, rhs: u32) -> Self
fn wrapping_shr(self, rhs: u32) -> Self
Panic-free bitwise shift-right; yields self >> mask(rhs)
, where mask
removes any high-order bits of rhs
that would cause the shift to
exceed the bit-width of the type.
Note that this is not the same as a rotate-right; the RHS of a wrapping
shift-right is restricted to the range of the type, rather than the bits
shifted out of the LHS being returned to the other end. The primitive
integer types all implement a rotate_right
function, which may be what
you want instead.
sourcefn wrapping_pow(self, rhs: u32) -> Self
fn wrapping_pow(self, rhs: u32) -> Self
Wrapping (modular) exponentiation. Computes self.pow(exp)
, wrapping
around at the boundary of the type.

sourcefn overflowing_div_euclid(self, rhs: Self) -> (Self, bool)
fn overflowing_div_euclid(self, rhs: Self) -> (Self, bool)
Calculates the quotient of Euclidean division self.div_euclid(rhs)

is 0.

fn overflowing_rem(self, rhs: Self) -> (Self, bool)
Calculates the remainder when self
is divided by rhs
.

§Panics
This function will panic if rhs
is 0.
sourcefn overflowing_rem_euclid(self, rhs: Self) -> (Self, bool)
fn overflowing_rem_euclid(self, rhs: Self) -> (Self, bool)
Overflowing Euclidean remainder. Calculates self.rem_euclid(rhs)
.
Returns a tuple of the remainder after dividing along with a boolean indicating whether an arithmetic overflow would occur. If an overflow would occur then 0 is returned.
§Panics
This function will panic if rhs is 0.
sourcefn overflowing_neg(self) -> (Self, bool)
fn overflowing_neg(self) -> (Self, bool)
Negates self, overflowing if this is equal to the minimum value.
Returns a tuple of the negated version of self along with a boolean
indicating whether an overflow happened. If self
is the minimum value
(e.g., i32::MIN
for values of type i32
), then the minimum value will
be returned again and true
will be returned for an overflow happening.
sourcefn overflowing_shl(self, rhs: u32) -> (Self, bool)
fn overflowing_shl(self, rhs: u32) -> (Self, bool)
Shifts self left by rhs
bits.
Returns a tuple of the shifted version of self along with a boolean indicating whether the shift value was larger than or equal to the number of bits. If the shift value is too large, then value is masked (N-1) where N is the number of bits, and this value is then used to perform the shift.
sourcefn overflowing_shr(self, rhs: u32) -> (Self, bool)
fn overflowing_shr(self, rhs: u32) -> (Self, bool)
Shifts self right by rhs
bits.
Returns a tuple of the shifted version of self along with a boolean indicating whether the shift value was larger than or equal to the number of bits. If the shift value is too large, then value is masked (N-1) where N is the number of bits, and this value is then used to perform the shift.
sourcefn overflowing_pow(self, rhs: u32) -> (Self, bool)
fn overflowing_pow(self, rhs: u32) -> (Self, bool)
Raises self to the power of exp
, using exponentiation by squaring.
Returns a tuple of the exponentiation along with a bool indicating whether an overflow happened.
sourcefn pow(self, rhs: u32) -> Self
fn pow(self, rhs: u32) -> Self
Raises self to the power of exp
, using exponentiation by squaring.
sourcefn div_euclid(self, rhs: Self) -> Self
fn div_euclid(self, rhs: Self) -> Self
Calculates the quotient of Euclidean division of self by rhs.
This computes the integer n
such that
self = n * rhs + self.rem_euclid(rhs)
, with
0 <= self.rem_euclid(rhs) < rhs
.
In other words, the result is self / rhs
rounded to the integer n
such that self >= n * rhs
. If self > 0
, this is equal to round
towards zero (the default in Rust); if self < 0
, this is equal to
round towards +/- infinity.

This function will panic if rhs
is 0 or the division results in
overflow.
sourcefn rem_euclid(self, rhs: Self) -> Self
fn rem_euclid(self, rhs: Self) -> Self
Calculates the least nonnegative remainder of self (mod rhs)
.
This is done as if by the Euclidean division algorithm – given
r = self.rem_euclid(rhs)
, self = rhs * self.div_euclid(rhs) + r
, and
0 <= r < abs(rhs)
.
§Panics
This function will panic if rhs
is 0 or the division results in
overflow.
