[SciPy-user] random number

[Razafindrakoto Jean Claude]

When running the example, I didn't get any errors. I'm running Pythonwin
with Python 2.3.2 and scipy 0.3 

>>> from scipy.stats.rand import *
>>> x=uniform(0,1e38)[0]
>>> x
5.9481523519433107e+037
>>> uniform(0,1e38)[0]
7.5203911045864378e+037
>>>

But if you change the seed, e.g 
>>> uniform(0,1e38)[1]
Traceback (most recent call last):
  File "<interactive input>", line 1, in ?
IndexError: index out of bounds

|Code below ?
|
|What I ment:
|
|    from scipy.stats.rand import *
|    uniform(0,1e38)[0]
|
|gives a float rn (e.g. 5.9437827355745297e+037) but
|
|    uniform(0,1e38)[0]
|
|gives
|
|    1.#INF
|
|(on win32, PythonWin, Python 2.3.4, scipy 0.3x). It seems that 'uniform'
|can't handle maximum values beyond 1e38.
