fixed. these tests run through now:

        [TestMethod]
        public void randTest()
        {
            // >>> np.random.rand(3,2)
            // array([[ 0.14022471,  0.96360618],  #random
            //        [ 0.37601032,  0.25528411],  #random
            //        [ 0.49313049,  0.94909878]]) #random
            // 

            np.random.seed(0);
            var given=  np.random.rand(1,2);
            var expected = "array([[0.5488135 , 0.71518937]])";

            Assert.AreEqual(expected, given.repr);
            np.random.seed(0);
            float x = np.random.rand();
            Assert.AreEqual(0.5488135039273248f, x);
        }


        [TestMethod]
        public void randnTest()
        {
            // >>> np.random.randn()
            // 2.1923875335537315 #random
            // 

            np.random.seed(0);
            var given =  np.random.randn();
            Assert.AreEqual(1.76405239f, given);
            // Two-by-four array of samples from N(3, 6.25):

            // >>> 2.5 * np.random.randn(2, 4) + 3
            // array([[-4.49401501,  4.00950034, -1.81814867,  7.29718677],  #random
            //        [ 0.39924804,  4.68456316,  4.99394529,  4.84057254]]) #random
            // 

            np.random.seed(0);
            var a =  2.5 * np.random.randn(1, 2) + 3;
             var expected= "array([[7.41013086, 4.00039302]])";
            Assert.AreEqual(expected, a.repr);

        }

the fix is gonna be released shortly. thanks for the bug reports!
