{"library":"Numpy","prompt":"Problem:\nI try to retrieve percentiles from an array with NoData values. In my case the Nodata values are represented by -3.40282347e+38. I thought a masked array would exclude this values (and other that is lower than 0)from further calculations. I succesfully create the masked array but for the np.percentile() function the mask has no effect.\n>>> DataArray = np.array(data)\n>>> DataArray\n([[ value, value...]], dtype=float32)\n>>> masked_data = ma.masked_where(DataArray < 0, DataArray)\n>>> percentile = 5\n>>> prob = np.percentile(masked_data, percentile)\n>>> print(prob)\n -3.40282347e+38\nA:\n<code>\nimport numpy as np\nDataArray = np.arange(-5.5, 10.5)\npercentile = 50\n</code>\nprob = ... # put solution in this variable\nBEGIN SOLUTION\n<code>\n"}
