impl i128
[src]

Wrapping (modular) addition. Computes self + other, wrapping around at the boundary of the type.

Examples

use extprim::i128::i128;

assert_eq!(i128::new(5).wrapping_add(i128::new(-6)), i128::new(-1));
assert_eq!(i128::max_value().wrapping_add(i128::one()), i128::min_value());

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

Examples

use extprim::i128::i128;

assert_eq!(i128::new(6).wrapping_sub(i128::new(13)), i128::new(-7));
assert_eq!(i128::min_value().wrapping_sub(i128::one()), i128::max_value());

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

use extprim::i128::i128;

assert_eq!(i128::new(7).wrapping_neg(), i128::new(-7));
assert_eq!(i128::min_value().wrapping_neg(), i128::min_value());

Calculates self + other.

Returns a tuple of the addition along with a boolean indicating whether an arithmetic overflow would occur. If an overflow would have occurred then the wrapped value is returned.

Examples

use extprim::i128::i128;

assert_eq!(i128::new(6).overflowing_add(i128::new(13)), (i128::new(19), false));
assert_eq!(i128::max_value().overflowing_add(i128::one()), (i128::min_value(), true));

Calculates self - other.

Returns a tuple of the subtraction along with a boolean indicating whether an arithmetic overflow would occur. If an overflow would have occurred then the wrapped value is returned.

Examples

use extprim::i128::i128;

assert_eq!(i128::new(3).overflowing_sub(i128::new(8)), (i128::new(-5), false));
assert_eq!(i128::min_value().overflowing_sub(i128::max_value()), (i128::one(), true));

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 (i128::MIN), then the minimum value will be returned again and true will be returned for an overflow happening.

Examples

use extprim::i128::i128;

assert_eq!(i128::new(7).overflowing_neg(), (i128::new(-7), false));
assert_eq!(i128::min_value().overflowing_neg(), (i128::min_value(), true));

Checked negation. Computes -self, returning None if self == MIN.

Examples

use extprim::i128::i128;

assert_eq!(i128::new(7).checked_neg(), Some(i128::new(-7)));
assert_eq!(i128::min_value().checked_neg(), None);

Saturating integer addition. Computes self + other, saturating at the numeric bounds instead of overflowing.

assert_eq!(i128::max_value().saturating_sub(i128::new(-2)), i128::max_value());
assert_eq!(i128::min_value().saturating_sub(i128::new(2)), i128::min_value());

Saturating integer negation. Computes -self, saturating at numeric bounds instead of overflowing.

Examples

use extprim::i128::i128;

impl i128
[src]

Examples

use extprim::i128::i128;

assert_eq!(i128::new(5).checked_add(i128::new(-6)), Some(i128::new(-1)));

impl i128
[src]

impl i128
[src]

Panic-free bitwise shift-left; yields self << (shift % 128).

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

use extprim::i128::i128;

assert_eq!(i128::new(1).wrapping_shl(127), i128::min_value());
assert_eq!(i128::new(19).wrapping_shl(256), i128::new(19));

Panic-free bitwise shift-right; yields `self >> (shift % 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. The primitive integer types all implement a rotate_right function, which may be what you want instead.

Examples

use extprim::i128::i128;

assert_eq!(i128::new(-50).wrapping_shr(2), i128::new(-13));
assert_eq!(i128::new(19).wrapping_shr(257), i128::new(9));

Shifts self left by other 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 by 0x7f, and this value is then used to perform the shift.

Examples

use extprim::i128::i128;

assert_eq!(i128::new(1).overflowing_shl(127), (i128::min_value(), false));
assert_eq!(i128::new(19).overflowing_shl(256), (i128::new(19), true));

Shifts self right by other 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 by 0x7f, and this value is then used to perform the shift.

Examples

use extprim::i128::i128;

assert_eq!(i128::new(-50).overflowing_shr(2), (i128::new(-13), false));

assert_eq!(i128::new(19).checked_shr(257), None);

impl i128
[src]

Calculates the multiplication of self and other.

Returns a tuple of the multiplication along with a boolean indicating whether an arithmetic overflow would occur. If an overflow would have occurred then the wrapped value is returned.

Examples

use extprim::i128::i128;

assert_eq!(i128::new(-6).overflowing_mul(i128::new(11)), (i128::new(-66), false));

let a = i128::from_parts(3, 1);

Examples

use extprim::i128::i128;

assert_eq!(i128::new(-6).checked_mul(i128::new(11)), Some(i128::new(-66)));

let a = i128::from_parts(3, 1);
let b = i128::from_parts(-1, 3);
assert_eq!(a.checked_mul(b), None);

impl i128
[src]

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

The only case where such wrapping can occur is when one divides MIN / -1; 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

Wrapping (modular) remainder. Computes self % other, 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. In such a case, this function returns 0.

Panics

This function will panic if other is 0.

Examples

use extprim::i128::i128;

assert_eq!(i128::new(100).wrapping_rem(i128::new(-8)), i128::new(4));

assert_eq!(i128::new(100).overflowing_div(i128::new(-8)), (i128::new(-12), false));
assert_eq!(i128::min_value().overflowing_div(i128::new(-1)), (i128::min_value(), true));

Calculates the remainder when self is divided by other.

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.

assert_eq!(i128::new(100).overflowing_rem(i128::new(-8)), (i128::new(4), false));

impl i128
[src]

Computes the absolute value of self.

Overflow behavior

The absolute value of i128::MIN 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 MIN without a panic.
