If I got it right from the docstring, 'np.longdouble', 'np.longfloat' are all in fact 'np.float128'. (numpy 1.5) However, I was surprised that float128 is not mentioned in the array of available types in the user guide. http://docs.scipy.org/doc/numpy/user/basics.types.html Is there a specific reason for this absence, or is just about visiting the documentation wiki ;-) ? Additionally, I don't know what are the writing guidelines of the user guide, but would it make sense to add some "new numpy 1.x" messages as in the Python doc. I'm thinking here of np.float16. I know it exists from messages on this mailing list but my 1.5 don't have it. Best, Pierre PS : I found float128 mentionned in the reference http://docs.scipy.org/doc/numpy/reference/arrays.scalars.html#built-in-scalar-types However, it is not as easily readable as the user guide (which makes sense !). Does the following statements mean that those types are not available on all platforms ? float96 96 bits, platform? float128 128 bits, platform?
