# Primitive Type i8 [−]

The 8-bit signed integer type.

See also the `std::i8` module.

However, please note that examples are shared between primitive integer types. So it's normal if you see usage of types like `i64` in there.

## Methods

#### `fn wrapping_add(self, rhs: i8) -> i8`1.0.0

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

# Examples

#### `fn wrapping_sub(self, rhs: i8) -> i8`1.0.0

# Examples

Basic usage:

assert_eq!((-2i8).wrapping_sub(127), 127);Run```

#### `fn wrapping_mul(self, rhs: i8) -> i8`1.0.0

Wrapping (modular) multiplication. Computes `self * other`, wrapping around at the boundary of the type.

#### `fn wrapping_div(self, rhs: i8) -> i8`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:

```assert_eq!(100u8.wrapping_div(10), 10);
assert_eq!((-128i8).wrapping_div(-1), -128);Run```

#### `fn wrapping_rem(self, rhs: i8) -> i8`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:

```assert_eq!(100i8.wrapping_rem(10), 0);
assert_eq!((-128i8).wrapping_rem(-1), 0);Run```

#### `fn wrapping_neg(self) -> i8`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:

```assert_eq!(100i8.wrapping_neg(), -100);
assert_eq!((-128i8).wrapping_neg(), -128);Run```

#### `fn wrapping_shl(self, rhs: u32) -> i8`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:

```assert_eq!((-1i8).wrapping_shl(7), -128);
assert_eq!((-1i8).wrapping_shl(8), -1);Run```

#### `fn wrapping_shr(self, rhs: u32) -> i8`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:

```assert_eq!((-128i8).wrapping_shr(7), -1);
assert_eq!((-128i8).wrapping_shr(8), -128);Run```

#### `fn wrapping_abs(self) -> i8`1.13.0

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!(100i8.wrapping_abs(), 100);
assert_eq!((-100i8).wrapping_abs(), 100);
assert_eq!((-128i8).wrapping_abs(), -128);
assert_eq!((-128i8).wrapping_abs() as u8, 128);Run```

#### `fn overflowing_add(self, rhs: i8) -> (i8, bool)`1.7.0

assert_eq!(i32::MIN.overflowing_sub(1), (i32::MAX, true));Run```

#### `fn overflowing_mul(self, rhs: i8) -> (i8, bool)`1.7.0

assert_eq!(1_000_000_000i32.overflowing_mul(10), (1410065408, true));Run```

#### `fn overflowing_div(self, rhs: i8) -> (i8, bool)`1.7.0

Calculates the divisor when `self` is divided by `rhs`.

Returns a tuple of the divisor along with a boolean indicating whether an arithmetic overflow would occur. If an overflow would occur then self is returned.

# Panics

# Examples

Basic usage

assert_eq!(5i32.overflowing_div(2), (2, false));

#### `fn overflowing_rem(self, rhs: i8) -> (i8, bool)`1.7.0

Calculates the remainder when `self` is divided by `rhs`.

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

#### `fn overflowing_neg(self) -> (i8, bool)`1.7.0

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

```use std::i32;

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

#### `fn overflowing_shl(self, rhs: u32) -> (i8, bool)`1.7.0

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

```assert_eq!(0x10i32.overflowing_shl(4), (0x100, false));
assert_eq!(0x10i32.overflowing_shl(36), (0x100, true));Run```

#### `fn overflowing_shr(self, rhs: u32) -> (i8, bool)`1.7.0

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

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

#### `fn overflowing_abs(self) -> (i8, bool)`1.13.0

Computes the absolute value of `self`.

Returns a tuple of the absolute 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:

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

#### `fn pow(self, exp: u32) -> i8`1.0.0

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

# Examples

Basic usage:

```let x: i32 = 2; // or any other integer type

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

#### `fn abs(self) -> i8`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:

```assert_eq!(10i8.abs(), 10);
assert_eq!((-10i8).abs(), 10);Run```

#### `fn signum(self) -> i8`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

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

#### `fn is_positive(self) -> bool`1.0.0

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

assert!(!(-10i8).is_positive());Run```

#### `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:

```assert!((-10i8).is_negative());
