# Primitive Type i64
1.0.0[−]

The 64-bit signed integer type.

## Implementations

### `impl i64`[src]

#### `pub const MIN: i64` 1.43.0[src]

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

# Examples

Basic usage:

    assert_eq!(i64::MIN, -9223372036854775808);

Run

#### `pub const MAX: i64` 1.43.0[src]

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

# Examples

Basic usage:

    assert_eq!(i64::MAX, 9223372036854775807);

Run

#### `pub const BITS: u32` 1.53.0[src]

The size of this integer type in bits.

# Examples

    assert_eq!(i64::BITS, 64);

Run

#### `pub fn from_str_radix(src: &str, radix: u32) -> Result<i64, ParseIntError>`[src]

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.

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`.

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.

#### `pub const fn wrapping_abs(self) -> i64` 1.13.0 (const: 1.32.0)[src]

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!(100i64.wrapping_abs(), 100);
    assert_eq!((-100i64).wrapping_abs(), 100);
    assert_eq!(i64::MIN.wrapping_abs(), i64::MIN);

pub const fn div_euclid(self, rhs: i64) -> i64` 1.38.0 (const: 1.52.0)[src]

Calculates the quotient of Euclidean division of `self` by `rhs`.

This computes the integer `q` such that `self = q * rhs + r`, with `r = self.rem_euclid(rhs)` and `0 <= r < abs(rhs)`.

In other words, the result is `self / rhs` rounded to the integer `q` such that `self >= q * 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 or the division results in overflow.

# Examples

Basic usage:

pub const fn rem_euclid(self, rhs: i64) -> i64` 1.38.0 (const: 1.52.0)[src]

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 or the division results in overflow.

Computes the absolute value of `self`.

# Overflow behavior

The absolute value of `i64::MIN` cannot be represented as an `i64`, 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 `i64::MIN` without a panic.
