Methods

impl i128

pub const fn min_value() -> i128

Returns the smallest value that can be represented by this integer type.

Examples

Basic usage:

assert_eq!(i128::min_value(), -170141183460469231731687303715884105728);

pub const fn max_value() -> i128

Returns the largest value that can be represented by this integer type.

Examples

Basic usage:

assert_eq!(i128::max_value(), 170141183460469231731687303715884105727);

pub fn from_str_radix(src: &str, radix: u32) -> Result<i128, ParseIntError>

Converts a string slice in a given base to an integer.

The string is expected to be an optional + or - sign followed by digits. Leading and trailing whitespace represent an error. Digits are a subset of these characters, depending on radix:

• 0-9
• a-z
• A-Z

Panics

This function panics if radix is not in the range from 2 to 36.

Examples

Basic usage:

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

pub fn wrapping_rem(self, rhs: i128) -> i128

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

This function will panic if rhs is 0.

Examples

Basic usage:

assert_eq!(100i128.wrapping_rem(10), 0);

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

assert_eq!(i128::min_value().wrapping_neg(), i128::min_value());

#[must_use = "this returns the result of the operation, without modifying the original"]

pub const fn wrapping_shl(self, rhs: u32) -> i128

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);

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 wrapping_abs(self) -> i128

Wrapping (modular) absolute value. Computes self.abs(), wrapping around at the boundary of the type.

The only case where such wrapping can occur is when one takes the absolute value of 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_abs(), 100);

assert_eq!(i128::MIN.overflowing_rem_euclid(-1), (0, true));

pub const fn overflowing_neg(self) -> (i128, 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.

Examples

Basic usage:

use std::i128;

assert_eq!(2i128.overflowing_neg(), (-2, false));
assert_eq!(i128::MIN.overflowing_neg(), (i128::MIN, true));

#[must_use = "this returns the result of the operation, without modifying the original"]

pub const fn overflowing_shl(self, rhs: u32) -> (i128, 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.

Examples

Basic usage:

assert_eq!(0x1i128.overflowing_shl(4), (0x10, false));
assert_eq!(0x1i32.overflowing_shl(36), (0x10, true));

#[must_use = "this returns the result of the operation, without modifying the original"]

pub const fn overflowing_shr(self, rhs: u32) -> (i128, 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.

Examples

Basic usage:

assert_eq!(0x10i128.overflowing_shr(4), (0x1, false));
assert_eq!(0x10i32.overflowing_shr(36), (0x1, true));

pub fn overflowing_abs(self) -> (i128, bool)

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));

#[must_use = "this returns the result of the operation, without modifying the original"]

pub fn overflowing_pow(self, exp: u32) -> (i128, 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.

Examples

Basic usage:

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

#[must_use = "this returns the result of the operation, without modifying the original"]

pub fn pow(self, exp: u32) -> i128

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);

#[must_use = "this returns the result of the operation, without modifying the original"]

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

🔬 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 * 2

#[must_use = "this returns the result of the operation, without modifying the original"]

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

🔬 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);

pub fn abs(self) -> i128

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);

pub fn signum(self) -> i128

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

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

pub const fn is_positive(self) -> bool

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

Examples

Basic usage:

assert!((-10i128).is_negative());
assert!(!10i128.is_negative());

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

assert_eq!(bytes, if cfg!(target_endian = "big") {

}

pub fn from_ne_bytes(bytes: [u8; 16]) -> i128
