.. function:: randu(state: uint32) -> uint32

   .. wp-function-tags::
      :kernel: true
      :python: true
      :differentiable: false

   Generate a uniform random unsigned 32-bit integer in the range [0, 2^32).
   
   In a kernel, advances ``state`` in place, so successive calls return different
   values; called from the Python scope, it does not modify ``state``, so repeated
   calls with the same ``state`` return the same value (see :func:`rand_init`).

.. function:: randu(state: uint32, low: uint32, high: uint32) -> uint32
   :noindex:

   .. wp-function-tags::
      :kernel: true
      :python: true
      :differentiable: false

   Generate a uniform random unsigned integer in the range [low, high).
   
   In a kernel, advances ``state`` in place, so successive calls return different
   values; called from the Python scope, it does not modify ``state``, so repeated
   calls with the same ``state`` return the same value (see :func:`rand_init`).
   Requires ``high > low``. Uses modulo reduction, so the distribution is slightly
   biased toward lower values for very large ranges.
