Wrapping (modular) subtraction. Computes self - other, wrapping around at the boundary of the type.

Examples

use extprim::u128::u128;

assert_eq!(u128::new(5).wrapping_sub(u128::new(6)), u128::max_value());

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

use extprim::u128::u128;

assert_eq!(u128::new(6).overflowing_add(u128::new(13)), (u128::new(19), false));

Calculates self - other.

Returns a tuple of the subtraction along with a boolean indicating whether an arithmetic overflow would occur. If an overflow would have occurred then the wrapped value is returned.

Examples

use extprim::u128::u128;

assert_eq!(u128::new(6).overflowing_sub(u128::new(5)), (u128::one(), false));
assert_eq!(u128::new(5).overflowing_sub(u128::new(6)), (u128::max_value(), true));

Saturating integer addition. Computes self + other, saturating at the numeric bounds instead of overflowing.

Examples

use extprim::u128::u128;

assert_eq!(u128::new(13).saturating_add(u128::new(7)), u128::new(20));

let huge_num = u128::from_str_radix("ccccccccbbbbbbbbaaaaaaaa99999999", 16).unwrap();

Examples

use extprim::u128::u128;

assert_eq!(u128::new(13).saturating_sub(u128::new(91)), u128::zero());

Wrapping (modular) negation. Computes -self, wrapping around at the boundary of the type.

Since unsigned types do not have negative equivalents all applications of this function will wrap (except for -0). For values smaller than the corresponding signed type's maximum the result is the same as casting the corresponding signed value. Any larger values are equivalent to MAX + 1 - (val - MAX - 1).

Examples

use extprim::u128::u128;

assert_eq!(u128::zero().wrapping_neg(), u128::zero());
