### Calculation

ema= (1-k) emaprev. + k * input;
k=2/(N+1);
N=period;

## Blanket Implementations

#### `type Error = Infallible`

The type returned in the event of a conversion error.

### `impl<T, U> TryInto<U> for T where    U: TryFrom<T>, `[src]

#### `type Error = <U as TryFrom<T>>::Error`

The type returned in the event of a conversion error.
