New issue 3354 by asmeu...@gmail.com: Minus sign in front of Piecewise is
not centered
http://code.google.com/p/sympy/issues/detail?id=3354
In [83]: -Piecewise((0, Abs(1/y) < 1), (1, Abs(y) < 1), (y*meijerg(((2, 1),
()), ((), (1, 0)), 1/y), True))
Out[83]:
⎧ │1│
-⎪ 0 for │─│ < 1
⎪ │y│
⎪
⎨ 1 for │y│ < 1
⎪
⎪ ╭─╮0, 2 ⎛2, 1 │ 1⎞
⎪y⋅│╶┐ ⎜ │ ─⎟ otherwise
⎩ ╰─╯2, 2 ⎝ 1, 0 │ y⎠
In [84]: pprint(-Piecewise((0, Abs(1/y) < 1), (1, Abs(y) < 1),
(y*meijerg(((2, 1), ()), ((), (1, 0)), 1/y), True)), use_unicode=False)
/ |1|
-| 0 for |-| < 1
| |y|
|
< 1 for |y| < 1
|
| __0, 2 /2, 1 | 1\
|y*/__ | | -| otherwise
\ \_|2, 2 \ 1, 0 | y/
The minus sign seems to be centered on the first expression, not the whole
thing.
