Implementations

The smallest value that can be represented by this integer type.

Examples

Basic usage:

assert_eq!(u128::MIN, 0);

Since unsigned types do not have negative equivalents all applications of this function will wrap (except for -0).

Any larger values are equivalent to MAX + 1 - (val - MAX - 1) where MAX is the corresponding signed type’s maximum.

Run

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.

The primitive integer types all implement a rotate_left function, which may be what you want instead.

Run

Calculates the least remainder of self (mod rhs).

Since, for the positive integers, all common definitions of division are equal, this is exactly equal to self % rhs.

Panics

This function will panic if rhs is 0.

Examples

Basic usage:

assert_eq!(7u128.rem_euclid(4), 3); // or any other integer type
Run
🔬This is a nightly-only experimental API. (int_roundings #88581)

Calculates the quotient of self and rhs, rounding the result towards negative infinity.

This is the same as performing self / rhs for all unsigned integers.

Panics

This function will panic if rhs is zero.

Examples

Basic usage:

#![feature(int_roundings)]
assert_eq!(7_u128.div_floor(4), 1);
Run
🔬This is a nightly-only experimental API. (int_roundings #88581)

Calculates the quotient of self and rhs, rounding the result towards positive infinity.

Panics

This function will panic if rhs is zero.

Overflow behavior

On overflow, this function will panic if overflow checks are enabled (default in debug mode) and wrap if overflow checks are disabled (default in release mode).

Examples

Basic usage:

#![feature(int_roundings)]
assert_eq!(7_u128.div_ceil(4), 2);
Run
🔬This is a nightly-only experimental API. (int_roundings #88581)

Calculates the smallest value greater than or equal to self that is a multiple of rhs.

Panics

This function will panic if rhs is zero.

Overflow behavior

On overflow, this function will panic if overflow checks are enabled (default in debug mode) and wrap if overflow checks are disabled (default in release mode).

Examples

Basic usage:

#![feature(int_roundings)]
assert_eq!(16_u128.next_multiple_of(8), 16);
assert_eq!(23_u128.next_multiple_of(8), 24);
Run
🔬This is a nightly-only experimental API. (int_roundings #88581)

Calculates the smallest value greater than or equal to self that is a multiple of rhs. Returns None if rhs is zero or the operation would result in overflow.

Examples

Basic usage:

#![feature(int_roundings)]
assert_eq!(16_u128.checked_next_multiple_of(8), Some(16));
assert_eq!(23_u128.checked_next_multiple_of(8), Some(24));
assert_eq!(1_u128.checked_next_multiple_of(0), None);
assert_eq!(u128::MAX.checked_next_multiple_of(2), None);
Run

Returns true if and only if self == 2^k for some k.

Examples

Basic usage:

assert!(16u128.is_power_of_two());
assert!(!10u128.is_power_of_two());
Run

Returns the smallest power of two greater than or equal to self.

When return value overflows (i.e., self > (1 << (N-1)) for type uN), it panics in debug mode and the return value is wrapped to 0 in release mode (the only situation in which method can return 0).

Examples

Basic usage:

assert_eq!(2u128.next_power_of_two(), 2);
assert_eq!(3u128.next_power_of_two(), 4);
Run

Returns the smallest power of two greater than or equal to n. If the next power of two is greater than the type’s maximum value, None is returned, otherwise the power of two is wrapped in Some.

Examples

Basic usage:

assert_eq!(2u128.checked_next_power_of_two(), Some(2));
assert_eq!(3u128.checked_next_power_of_two(), Some(4));
assert_eq!(u128::MAX.checked_next_power_of_two(), None);
Run
🔬This is a nightly-only experimental API. (wrapping_next_power_of_two #32463)

Returns the smallest power of two greater than or equal to n. If the next power of two is greater than the type’s maximum value, the return value is wrapped to 0.

Examples

Basic usage:

#![feature(wrapping_next_power_of_two)]

assert_eq!(2u128.wrapping_next_power_of_two(), 2);
assert_eq!(3u128.wrapping_next_power_of_two(), 4);
assert_eq!(u128::MAX.wrapping_next_power_of_two(), 0);
Run

Run

Return the memory representation of this integer as a byte array in native byte order.
