fn wrapping_div(self, rhs: isize) -> isize

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: isize) -> isize

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) -> isize

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) -> isize

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) -> isize

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 overflowing_add(self, rhs: isize) -> (isize, bool)

Calculates self + rhs

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

Basic usage

fn main() { use std::i32; assert_eq!(5i32.overflowing_add(2), (7, false)); assert_eq!(i32::MAX.overflowing_add(1), (i32::MIN, true)); }

assert_eq!(5i32.overflowing_add(2), (7, false));
assert_eq!(i32::MAX.overflowing_add(1), (i32::MIN, true));

fn overflowing_sub(self, rhs: isize) -> (isize, bool)

use std::i32;

assert_eq!(5i32.overflowing_sub(2), (3, false));
assert_eq!(i32::MIN.overflowing_sub(1), (i32::MAX, true));

fn overflowing_mul(self, rhs: isize) -> (isize, bool)

assert_eq!(5i32.overflowing_mul(2), (10, false));
assert_eq!(1_000_000_000i32.overflowing_mul(10), (1410065408, true));

fn overflowing_div(self, rhs: isize) -> (isize, bool)

use std::i32;

assert_eq!(5i32.overflowing_rem(2), (1, false));
assert_eq!(i32::MIN.overflowing_rem(-1), (0, true));

fn overflowing_neg(self) -> (isize, bool)

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 (e.g. i32::MIN for values of type i32), then the minimum value will be returned again and true will be returned for an overflow happening.

Examples

Basic usage

fn main() { use std::i32; assert_eq!(2i32.overflowing_neg(), (-2, false)); assert_eq!(i32::MIN.overflowing_neg(), (i32::MIN, true)); }

assert_eq!(2i32.overflowing_neg(), (-2, false));
assert_eq!(i32::MIN.overflowing_neg(), (i32::MIN, true));

fn overflowing_shl(self, rhs: u32) -> (isize, bool)

Shifts self left by rhs 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 (N-1) where N is the number of bits, and this value is then used to perform the shift.

Examples

Basic usage

fn main() { assert_eq!(0x10i32.overflowing_shl(4), (0x100, false)); assert_eq!(0x10i32.overflowing_shl(36), (0x100, true)); }

fn overflowing_shr(self, rhs: u32) -> (isize, bool)

Shifts self right by rhs 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 (N-1) where N is the number of bits, and this value is then used to perform the shift.

Examples

Basic usage

fn main() { assert_eq!(0x10i32.overflowing_shr(4), (0x1, false)); assert_eq!(0x10i32.overflowing_shr(36), (0x1, true)); }

assert_eq!(0x10i32.overflowing_shr(4), (0x1, false));
assert_eq!(0x10i32.overflowing_shr(36), (0x1, true));

fn pow(self, exp: u32) -> isize

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) -> isize

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);

assert_eq!(10i8.signum(), 1);
assert_eq!(0i8.signum(), 0);
assert_eq!((-10i8).signum(), -1);

fn is_positive(self) -> bool

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());
