|
|
|
|
A template functions that return the absolute value.
|
|
|
|
```cpp
|
|
template <typename T>
|
|
ETL_CONSTEXPR T absolute(T value)
|
|
```
|
|
**Return**
|
|
The absolute of `value`.
|
|
|
|
If T is `int8_t`:-
|
|
`0` => `0`
|
|
`127` => `127`
|
|
`-127` => `127`
|
|
|
|
**Error**
|
|
Asserts if `value == etl::integral_limits<T>::min`.

```cpp
|
|
template <typename T>
|
|
ETL_CONSTEXPR etl::make_unsigned_t<T> absolute_unsigned(T value)
|
|
```
|
|
**Return**
|
|
The absolute of `value`, cast to the unsigned version of type `T`.
|
|
|
|
If T is `int8_t`:-
|
|
|
|
Return type is `etl::make_unsigned_t<T>`
|
|
`0` => `0`
|
|
`127` => `127`
|
|
`-127` => `127`
|
|
`-128` => `128`
