random(size=None, dtype=None, **kwargs)[source]

Return random floats in the half-open interval [0.0, 1.0).

Results are from the “continuous uniform” distribution over the stated interval. To sample \(\mathrm{Uniform}[a, b), b > a\) multiply the output of random by (b-a) and add a:

(b - a) * random() + a

Parameters

  • size (int or tuple of ints, optional) –

    Output shape. If the given shape is, e.g., (m, n, k), then m * n * k samples

    are drawn.

    Default is None, in which case a single value is returned.

  • dtype (dtype, optional) – Desired dtype of the result, only float64 and float32 are supported. The default value is np.float64.

  • **kwargs – Keywords argument used when creating the returned object, such as units, name, title, …

Returns

random – Array of random floats of shape size (unless size=None, in which case a single float is returned).
