New issue 2317 by [email protected]: loggamma needs testing
http://code.google.com/p/sympy/issues/detail?id=2317
The current test suite is:
def test_loggamma():
pass
And things like loggamma(2,3) don't raise an error; nargs is 1 so it
should. The error is not raised until evaluation:
h[9] >>> loggamma(2,3)
loggamma(2, 3)
h[10] >>> _.n()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "sympy\core\evalf.py", line 1041, in evalf
result = evalf(self, prec+4, options)
File "sympy\core\evalf.py", line 980, in evalf
r = x._eval_evalf(prec)._mpf_, None, prec, None
File "sympy\core\function.py", line 239, in _eval_evalf
v = func(*args)
TypeError: f() takes exactly 1 argument (2 given)
