assert_eq!(U256::MAX.wrapping_mul(U256::new(2)), U256::MAX - 1);

pub fn wrapping_div(self, rhs: Self) -> Self

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).

Examples

Basic usage:

assert_eq!(U256::new(100).wrapping_div_euclid(U256::new(10)), U256::new(10));

pub fn wrapping_rem_euclid(self, rhs: Self) -> Self

Wrapping Euclidean modulo. Computes self.rem_euclid(rhs). 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).

assert_eq!(U256::new(100).wrapping_rem_euclid(U256::new(10)), U256::new(0));

pub fn wrapping_neg(self) -> Self

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

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.

Examples

Basic usage:

Please note that this example is shared between integer types. Which explains why i8 is used here.

assert_eq!(U256::new(100).wrapping_neg(), (-100i128).as_u256());
assert_eq!(
    U256::from_words(i128::MIN as _, 0).wrapping_neg(),
    U256::from_words(i128::MIN as _, 0),
);

pub 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 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 maybe what you want instead.

Examples

Basic usage:

assert_eq!(U256::new(1).wrapping_shl(7), U256::new(128));
assert_eq!(U256::new(1).wrapping_shl(128), U256::from_words(1, 0));
assert_eq!(U256::new(1).wrapping_shl(256), U256::new(1));

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

Examples

Basic usage:

assert_eq!(U256::from_words(128, 0).wrapping_shr(128), U256::new(128));

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!(U256::new(7).div_euclid(U256::new(4)), U256::new(1));

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

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!(U256::new(7).rem_euclid(U256::new(4)), U256::new(3));

pub fn is_power_of_two(self) -> bool

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

Examples

Basic usage:

assert!(U256::new(16).is_power_of_two());
assert!(!U256::new(10).is_power_of_two());

pub fn next_power_of_two(self) -> Self

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 return value is wrapped to 0 in release mode (the only situation in which method can return 0).

Examples

Basic usage:

assert_eq!(U256::new(2).next_power_of_two(), U256::new(2));
assert_eq!(U256::new(3).next_power_of_two(), U256::new(4));

pub fn checked_next_power_of_two(self) -> Option<Self>

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!(U256::new(2).checked_next_power_of_two(), Some(U256::new(2)));
assert_eq!(U256::new(3).checked_next_power_of_two(), Some(U256::new(4)));
assert_eq!(U256::MAX.checked_next_power_of_two(), None);
