# Trait num::integer::Average

``````pub trait Average: Integer {
// Required methods
fn average_ceil(&self, other: &Self) -> Self;
fn average_floor(&self, other: &Self) -> Self;
}``````
Expand description

Provides methods to compute the average of two integers, without overflows.

## Required Methods§

source

#### fn average_ceil(&self, other: &Self) -> Self

Returns the ceiling value of the average of `self` and `other`. – `⌈(self + other)/2⌉`

##### §Examples
``````use num_integer::Average;

assert_eq!(( 3).average_ceil(&10),  7);
assert_eq!((-2).average_ceil(&-5), -3);
assert_eq!(( 4).average_ceil(& 4),  4);

assert_eq!(u8::max_value().average_ceil(&2), 129);
assert_eq!(i8::min_value().average_ceil(&-1), -64);
assert_eq!(i8::min_value().average_ceil(&i8::max_value()), 0);``````
source

#### fn average_floor(&self, other: &Self) -> Self

Returns the floor value of the average of `self` and `other`. – `⌊(self + other)/2⌋`

##### §Examples
``````use num_integer::Average;

assert_eq!(( 3).average_floor(&10),  6);
assert_eq!((-2).average_floor(&-5), -4);
assert_eq!(( 4).average_floor(& 4),  4);

assert_eq!(u8::max_value().average_floor(&2), 128);
assert_eq!(i8::min_value().average_floor(&-1), -65);
assert_eq!(i8::min_value().average_floor(&i8::max_value()), -1);``````
