-
sqrt
(x, out=None, **kwargs)¶ Return the non-negative square-root of an array, element-wise.
- Parameters
x (ndarray or scalar) – The values whose square-roots are required.
out (ndarray, or None, optional) – A location into which the result is stored. If provided, it must have a shape that the inputs broadcast to. If not provided or None, a freshly-allocated array is returned.
- Returns
y – An array of the same shape as x, containing the positive square-root of each element in x. This is a scalar if x is a scalar.

This function only supports input type of float.
Examples
