[src]

Wrapping (modular) division. Computes self / rhs, wrapping around at the boundary of the type.

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.

Panics

This function will panic if rhs is 0.

Examples

Basic usage:

assert_eq!((-128i8).wrapping_div(-1), -128);Run

pub fn wrapping_div_euclid(self, rhs: i128) -> i128[src]

🔬 This is a nightly-only experimental API. (euclidean_division #49048)

Wrapping Euclidean division. Computes self.div_euclid(rhs), wrapping around at the boundary of the type.

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.

Panics

This function will panic if rhs is 0.

Examples

Basic usage:

#![feature(euclidean_division)]

pub fn wrapping_rem(self, rhs: i128) -> i128
1.2.0
[src]

Wrapping (modular) remainder. Computes self % rhs, wrapping around at the boundary of the type.

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.

Panics

This function will panic if rhs is 0.

Examples

Basic usage:

assert_eq!(100i128.wrapping_rem(10), 0);
assert_eq!((-128i8).wrapping_rem(-1), 0);Run

Examples

Basic usage:

pub const fn wrapping_neg(self) -> i128
1.2.0
[src]

Wrapping (modular) negation. Computes -self, wrapping around at the boundary of the type.

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.

Examples

Basic usage:

assert_eq!(100i128.wrapping_neg(), -100);
assert_eq!(i128::min_value().wrapping_neg(), i128::min_value());Run

pub const fn wrapping_shl(self, rhs: u32) -> i128
1.2.0
[src]

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 bitwidth 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.

Examples

Basic usage:

assert_eq!((-1i128).wrapping_shl(7), -128);
assert_eq!((-1i128).wrapping_shl(128), -1);Run

pub const fn wrapping_shr(self, rhs: u32) -> i128
1.2.0
[src]

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 bitwidth 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.

pub fn overflowing_abs(self) -> (i128, bool)
1.13.0
[src]

Computes the absolute value of self.

Returns a tuple of the absolute version of self along with a boolean indicating whether an overflow happened. If self is the minimum value (e.g., i128::MIN for values of type i128), then the minimum value will be returned again and true will be returned for an overflow happening.

Examples

Basic usage:

assert_eq!(10i128.overflowing_abs(), (10, false));
assert_eq!((-10i128).overflowing_abs(), (10, false));
assert_eq!((i128::min_value()).overflowing_abs(), (i128::min_value(), true));Run

pub fn overflowing_pow(self, exp: u32) -> (i128, bool)
1.34.0
[src]

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.

Examples

Basic usage:

assert_eq!(3i128.overflowing_pow(4), (81, false));
assert_eq!(3i8.overflowing_pow(5), (-13, true));Run

pub fn pow(self, exp: u32) -> i128
1.0.0
[src]

Raises self to the power of exp, using exponentiation by squaring.

Examples

Basic usage:

let x: i128 = 2; // or any other integer type

assert_eq!(x.pow(5), 32);Run

pub fn div_euclid(self, rhs: i128) -> i128[src]

🔬 This is a nightly-only experimental API. (euclidean_division #49048)

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.

Panics

This function will panic if rhs is 0.

Examples

Basic usage:

#![feature(euclidean_division)]
let a: i128 = 7; // or any other integer type
let b = 4;

assert_eq!(a.div_euclid(b), 1); // 7 >= 4 * 1
assert_eq!(a.div_euclid(-b), -1); // 7 >= -4 * -1
assert_eq!((-a).div_euclid(b), -2); // -7 >= 4 * -2
assert_eq!((-a).div_euclid(-b), 2); // -7 >= -4 * 2Run

pub fn rem_euclid(self, rhs: i128) -> i128[src]

🔬 This is a nightly-only experimental API. (euclidean_division #49048)

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.

Examples

Basic usage:

#![feature(euclidean_division)]
let a: i128 = 7; // or any other integer type
let b = 4;

assert_eq!(a.rem_euclid(b), 3);
assert_eq!((-a).rem_euclid(b), 1);
assert_eq!(a.rem_euclid(-b), 3);
assert_eq!((-a).rem_euclid(-b), 1);Run

pub fn abs(self) -> i128
1.0.0
[src]

Computes the absolute value of self.

Overflow behavior

The absolute value of i128::min_value() cannot be represented as an i128, and attempting to calculate it will cause an overflow. This means that code in debug mode will trigger a panic on this case and optimized code will return i128::min_value() without a panic.

Examples

Basic usage:

assert_eq!(10i128.abs(), 10);
assert_eq!((-10i128).abs(), 10);Run

pub fn signum(self) -> i128
1.0.0
[src]

Returns a number representing sign of self.

  • 0 if the number is zero
  • 1 if the number is positive
  • -1 if the number is negative

Examples

Basic usage:

assert_eq!(10i128.signum(), 1);
assert_eq!(0i128.signum(), 0);
assert_eq!((-10i128).signum(), -1);Run

pub const fn is_positive(self) -> bool
1.0.0
[src]

assert!(!(-10i128).is_positive());Run

pub const fn is_negative(self) -> bool
1.0.0
[src]

Returns true if self is negative and false if the number is zero or positive.

Examples

Basic usage:

pub fn to_be_bytes(self) -> [u8; 16]

1.32.0
[src]

Examples
