NumPy's `square(~)` method computes the square of each value in the input array, that is, `p^2` for every value `p`.

WARNING

Prefer **2 over the square method

If you don't need parameters 2 and 3, then simply use `a ** 2` instead for a performance boost.

# Parameters

1. `a` | `array_like`

The input array.

2. `out` | `Numpy array` | `optional`

Instead of creating a new array, you can place the computed result into the array specified by `out`.

3. `where` | `array` of `boolean` | `optional`

Values that are flagged as False will be ignored, that is, their original value will be uninitialized. If you specified the out parameter, the behavior is slightly different - the original value will be kept intact.

# Return value

A scalar is returned if `a` is a scalar, otherwise a NumPy array is returned.

# Examples

## Basic usage

``` a = np.array([1, 3, 5])np.square(a) array([ 1, 9, 25]) ```
