numpy ndarray convert function tolist()

A float32 ndarray remained 3 decimal places can't be convert to a list properly by using tolist(), but float64 can.

import numpy as np
a = np.random.random((5,))
a64 = a.astype(np.float64)
out64 = np.around(a64, 3)
outlist64 = out64.tolist()
print(outlist64)

a32 = a.astype(np.float32)
out32 = np.around(a32, 3)
outlist32 = out.tolist()
print(outlist32)
