Primitive Type i64 []

The 64-bit signed integer type.

See also the std::i64 module.

However, please note that examples are shared between primitive integer types. So it's normal if you see usage of types like i8 in there.

Methods

fn wrapping_div(self, rhs: i64) -> i64
1.2.0

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 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.

Examples

Basic usage:

fn main() { assert_eq!(100u8.wrapping_div(10), 10); assert_eq!((-128i8).wrapping_div(-1), -128); }
assert_eq!(100u8.wrapping_div(10), 10);

fn wrapping_rem(self, rhs: i64) -> i64
1.2.0

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 (where MIN is the negative minimal value). In such a case, this function returns 0.

Panics

This function will panic if rhs is 0.

Examples

Basic usage:

fn main() { assert_eq!(100i8.wrapping_rem(10), 0); assert_eq!((-128i8).wrapping_rem(-1), 0); }
assert_eq!(100i8.wrapping_rem(10), 0);
assert_eq!((-128i8).wrapping_rem(-1), 0);

fn wrapping_neg(self) -> i64
1.2.0

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:

fn main() { assert_eq!(100i8.wrapping_neg(), -100); assert_eq!((-128i8).wrapping_neg(), -128); }
assert_eq!(100i8.wrapping_neg(), -100);
assert_eq!((-128i8).wrapping_neg(), -128);

fn wrapping_shl(self, rhs: u32) -> i64
1.2.0

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.

Examples

Basic usage:

fn main() { assert_eq!((-1i8).wrapping_shl(7), -128); assert_eq!((-1i8).wrapping_shl(8), -1); }
assert_eq!((-1i8).wrapping_shl(7), -128);
assert_eq!((-1i8).wrapping_shl(8), -1);

fn wrapping_shr(self, rhs: u32) -> i64
1.2.0

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:

fn main() { assert_eq!((-128i8).wrapping_shr(7), -1); assert_eq!((-128i8).wrapping_shr(8), -128); }
assert_eq!((-128i8).wrapping_shr(7), -1);
assert_eq!((-128i8).wrapping_shr(8), -128);

fn wrapping_abs(self) -> i64

Unstable (no_panic_abs #35057)

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:

#![feature(no_panic_abs)] fn main() { assert_eq!(100i8.wrapping_abs(), 100); assert_eq!((-100i8).wrapping_abs(), 100); assert_eq!((-128i8).wrapping_abs(), -128); assert_eq!((-128i8).wrapping_abs() as u8, 128); }

assert_eq!(100i8.wrapping_abs(), 100);
assert_eq!((-100i8).wrapping_abs(), 100);
assert_eq!((-128i8).wrapping_abs(), -128);

Examples

Basic usage:

#![feature(no_panic_abs)] fn main() { assert_eq!(10i8.overflowing_abs(), (10,false)); assert_eq!((-10i8).overflowing_abs(), (10,false)); assert_eq!((-128i8).overflowing_abs(), (-128,true)); }

assert_eq!(10i8.overflowing_abs(), (10,false));
assert_eq!((-10i8).overflowing_abs(), (10,false));
assert_eq!((-128i8).overflowing_abs(), (-128,true));

fn pow(self, exp: u32) -> i64
1.0.0

Raises self to the power of exp, using exponentiation by squaring.

Examples

Basic usage:

fn main() { let x: i32 = 2; // or any other integer type assert_eq!(x.pow(4), 16); }
let x: i32 = 2; // or any other integer type

assert_eq!(x.pow(4), 16);

fn abs(self) -> i64
1.0.0

Computes the absolute value of self.

Overflow behavior

The absolute value of i32::min_value() 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_value() without a panic.

Examples

Basic usage:

fn main() { assert_eq!(10i8.abs(), 10); assert_eq!((-10i8).abs(), 10); }
assert_eq!(10i8.abs(), 10);
assert_eq!((-10i8).abs(), 10);

fn signum(self) -> i64
1.0.0

Returns a number representing sign of self.

  • 0 if the number is zero
  • 1 if the number is positive
  • -1 if the number is negative

Examples

Basic usage:

fn main() { assert_eq!(10i8.signum(), 1); assert_eq!(0i8.signum(), 0); assert_eq!((-10i8).signum(), -1); }
assert_eq!(10i8.signum(), 1);
assert_eq!(0i8.signum(), 0);
assert_eq!((-10i8).signum(), -1);

fn is_positive(self) -> bool
1.0.0

Returns true if self is positive and false if the number is zero or negative.

Examples

Basic usage:

fn main() { assert!(10i8.is_positive()); assert!(!(-10i8).is_positive()); }
assert!(10i8.is_positive());
assert!(!(-10i8).is_positive());

fn is_negative(self) -> bool
1.0.0

Returns true if self is negative and false if the number is zero or positive.

Examples

Basic usage:

fn main() { assert!((-10i8).is_negative()); assert!(!10i8.is_negative()); }
assert!((-10i8).is_negative());
assert!(!10i8.is_negative());
