New issue 2320 by ondrej.c...@gmail.com: hydrogen doctest failures
http://code.google.com/p/sympy/issues/detail?id=2320
I am getting hydrogen doctest failures on my machine:
_________________________ sympy.physics.hydrogen.R_nl
__________________________
File "/home/certik1/repos/sympy/sympy/physics/hydrogen.py", line 32, in
sympy.physics.hydrogen.R_nl
Failed example:
R_nl(3, 0, r)
Expected:
2*3**(1/2)*(3 - 2*r + 2*r**2/9)*exp(-r/3)/27
Got:
-2*3**(1/2)*(1 - (2 - 2*r/3)*(4 - 2*r/3)/2)*exp(-r/3)/27
**********************************************************************
File "/home/certik1/repos/sympy/sympy/physics/hydrogen.py", line 41, in
sympy.physics.hydrogen.R_nl
Failed example:
R_nl(3, 0, r, Z=47)
Expected:
94*141**(1/2)*(3 - 94*r + 4418*r**2/9)*exp(-47*r/3)/27
Got:
-94*141**(1/2)*(1 - (2 - 94*r/3)*(4 - 94*r/3)/2)*exp(-47*r/3)/27
============= tests finished: 2 passed, 1 failed, in 1.07 seconds

DO *NOT* COMMIT!
I'll try to bisect it to see where this is coming from. If it's Python
version related issue, or some changes inside sympy.
