Comment #3 on issue 2230 by [email protected]: Problem in is_Function ans
is_Number
http://code.google.com/p/sympy/issues/detail?id=2230
Interesting, about lowercased `is_number`, I did not know about it.
Additionally
What about `sin(1).is_Function` and `sin.is_Function` behaviour, I found
right now, that it can be because of:
class Application(Basic):
"""
Base class for applied functions.
Instances of Application represent the result of applying an
application of
any type to any object.
"""
__metaclass__ = FunctionClass
__slots__ = []
is_Function = True
...
is not it?
Also taking advantage of the opportunity can I ask more about doc string:
is it means that `sin` is not class but rather the class instance?
And one more question, is it bug or not:
IPython console for SymPy 0.6.7-git (Python 2.6.6)
These commands were executed:
>>> from __future__ import division
>>> from sympy import *
>>> x, y, z, t = symbols('x y z t')
>>> k, m, n = symbols('k m n', integer=True)
>>> f, g, h = map(Function, 'fgh')
Documentation can be found at http://sympy.org/
In [1]: max(x, y, z)
Out[1]: z
In [2]: max(y, z)
Out[2]: z
Thanks
