[masaaldosey]

Closes #8975.

Simply added this suggestion by @kc611.

Thank you @masaaldosey for your contributions, could you please also add the original example in the issue (#8975 (comment)) as a test?

The tests for the uniform distribution in the old random number generator API are present at:

numba/numba/tests/test_random.py

Lines 520 to 533 in dd082ca

	def test_random_uniform(self):
	self._check_uniform(jit_binary("random.uniform"), get_py_state_ptr())
	def test_numpy_uniform(self):
	self._check_uniform(jit_binary("np.random.uniform"), get_np_state_ptr())
	def test_numpy_uniform_kwargs(self):
	self._check_any_distrib_kwargs(
	jit_with_kwargs("np.random.uniform", ['low', 'high']),
	get_np_state_ptr(),
	'uniform',
	paramlist=[{'low': 1.5, 'high': 1e6},
	{'low': -2.5, 'high': 1e3},
	{'low': 1.5, 'high': -2.5}])

Nice username btw 😄

@kc611 haha! thank you! have added the test. please let me know if more changes are needed 😸

[kc611]

The size needs to check for () and not None.

Suggested change

	paramlist=[{'low' : 0.0, 'high' : 1.0, 'size': None}])
	paramlist=[{'low' : 0.0, 'high' : 1.0, 'size': ()}])

Hi @kc611! I applied the suggestion and ran the test locally. The test fails because of dtype mismatch (see attached screenshot). I think I need to fiddle around with this method. But I am not sure. Could you help me with this?
