#### pub const BITS: u32 = 32u32

The size of this integer type in bits.

##### Examples

    assert_eq!(i32::BITS, 32);

Run
1.0.0 · source

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

    assert_eq!(i32::from_str_radix("A", 16), Ok(10));

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

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.

#### pub const fn wrapping_div_euclid(self, rhs: Self) -> Self

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:

#### pub const fn wrapping_rem(self, rhs: Self) -> Self

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.

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

Wrapping Euclidean remainder. Computes `self.rem_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). In this case, this method returns 0.

##### Panics

This function will panic if `rhs` is 0.

##### Examples

Basic usage:

    assert_eq!(100i32.wrapping_rem_euclid(10), 0);
    assert_eq!((-128i8).wrapping_rem_euclid(-1), 0);

#### pub const fn wrapping_neg(self) -> Self

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!(100i32.wrapping_neg(), -100);

#### pub const 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 may be what you want instead.

##### Examples

Basic usage:

    assert_eq!((-1i32).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. The primitive integer types all implement a `rotate_right` function, which may be what you want instead.

#### pub const fn wrapping_abs(self) -> Self

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:

#### pub fn carrying_add(self, rhs: Self, carry: bool) -> (Self, bool)

🔬This is a nightly-only experimental API. (`bigint_helper_methods` #85532)

Calculates `self` + `rhs` + `carry` and checks for overflow.

Performs “ternary addition” of two integer operands and a carry-in bit, and returns a tuple of the sum along with a boolean indicating whether an arithmetic overflow would occur. On overflow, the wrapped value is returned.

This allows chaining together multiple additions to create a wider addition, and can be useful for bignum addition. This method should only be used for the most significant word; for the less significant words the unsigned method `u32::carrying_add` should be used.

The output boolean returned by this method is not a carry flag, and should not be added to a more significant word.

If the input carry is false, this method is equivalent to `overflowing_add`.

Performs “ternary subtraction” by subtracting both an integer operand and a borrow-in bit from `self`, and returns a tuple of the difference along with a boolean indicating whether an arithmetic overflow would occur. On overflow, the wrapped value is returned.

This allows chaining together multiple subtractions to create a wider subtraction, and can be useful for bignum subtraction. This method should only be used for the most significant word; for the less significant words the unsigned method `u32::borrowing_sub` should be used.

#### pub const fn abs(self) -> Self

Computes the absolute value of `self`.

##### Overflow behavior

The absolute value of `i32::MIN` cannot be represented as an `i32`, 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 `i32::MIN` without a panic.

##### Examples

Basic usage:

    assert_eq!(10i32.abs(), 10);
    assert_eq!((-10i32).abs(), 10);

#### pub const fn abs_diff(self, other: Self) -> u32

Computes the absolute difference between `self` and `other`.

    assert_eq!(100i32.abs_diff(80), 20u32);
    assert_eq!(100i32.abs_diff(110), 10u32);
