)Calculates self

+ carry
and returns a tuple containing
the sum and the output carry.
Performs “ternary addition” of two integer operands and a carry-in bit, and returns an output integer and a carry-out bit. This allows chaining together multiple additions to create a wider addition, and can be useful for bignum addition.

equal to the overflow flag. Note that although carry and overflow
flags are similar for unsigned integers, they are different for
signed integers.

let mut carry = 0;
for d in little_endian_digits.iter_mut() {
(*d, carry) = d.carrying_mul(multiplicand, carry);
}
if carry != 0 {
little_endian_digits.push(carry);
}
}
let mut v = vec![10, 20];
scalar_mul_eq(&mut v, 3);
assert_eq!(v, [30, 60]);
assert_eq!(0x87654321_u64 * 0xFEED, 0x86D3D159E38D);
let mut v = vec![0x4321, 0x8765];
scalar_mul_eq(&mut v, 0xFEED);
assert_eq!(v, [0xE38D, 0xD159, 0x86D3]);
If carry
is zero, this is similar to overflowing_mul
,
except that it gives the value of the overflow instead of just whether one happened:
#![feature(bigint_helper_methods)]
let r = u8::carrying_mul(7, 13, 0);
assert_eq!((r.0, r.1 != 0), u8::overflowing_mul(7, 13));
let r = u8::carrying_mul(13, 42, 0);
assert_eq!((r.0, r.1 != 0), u8::overflowing_mul(13, 42));
The value of the first field in the returned tuple matches what you’d get
by combining the wrapping_mul
and
wrapping_add
methods:
#![feature(bigint_helper_methods)]
assert_eq!(
789_u16.carrying_mul(456, 123).0,
789_u16.wrapping_mul(456).wrapping_add(123),
);
const: unstable · sourcepub fn midpoint(self, rhs: u32) -> u32
🔬This is a nightly-only experimental API. (num_midpoint
)
pub fn midpoint(self, rhs: u32) -> u32
num_midpoint
)Calculates the middle point of self
and rhs
.
midpoint(a, b)
is (a + b) >> 1
as if it were performed in a
sufficiently-large signed integral type. This implies that the result is
always rounded towards negative infinity and that no overflow will ever occur.
Examples
#![feature(num_midpoint)]
assert_eq!(0u32.midpoint(4), 2);
assert_eq!(1u32.midpoint(4), 2);
