hi all, I have tried the example from numpy/add_newdocs.py
np.ldexp(5., 2) but instead of the 20 declared there it yields TypeError: function not supported for these types, and can't coerce safely to supported types
I have tried arrays but it yields same error
np.ldexp(np.array([5., 2.]), np.array([2, 1]))
Traceback (innermost last): File "<stdin>", line 1, in <module> TypeError: function not supported for these types, and can't coerce safely to supported types
So, how can I use ldexp? np.__version__ = '1.4.0.dev6972'
Thank you in advance, D.

Which OS/Compiler are you using ?

I have updated numpy to latest '1.4.0.dev7008', but the bug still remains. I use KUBUNTU 9.04, compilers - gcc (using build-essential), gfortran. D.

Can you post the build output (after having removed the build directory : rm -rf build && python setup.py build &> build.log) ?

Worksforme on Ubuntu 9.04, on python2.6 and python2.5. Should be the same platform.

This was on 32-bit machine. I can reproduce this on a 64-bit platform, current SVN head:
np.ldexp(5, 2)
Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: function not supported for these types, and can't coerce safely to supported types
np.ldexp(5, np.int32(2))
20.0
np.ldexp.types
['fi->f', 'di->d', 'gi->g']
So for some reason the second argument tries to cast Python int to int64, and there's no loop to handle this.
Hi Dmitrey

I could not reproduce the problem on current SVN:
In [6]: np.ldexp(5., 2) Out[6]: 20.0
In [7]: np.ldexp(np.array([5., 2.]), np.array([2, 1])) Out[7]: array([ 20., 4.])
