Comment(by staticfloat):

 I thought that was the problem as well, however the following works:


 {{{
 >>> type( 100L )
 <type 'long'>
 >>> np.log( 100L )
 4.6051701859880918
 }}}

 So clearly, np.log either works with longs, or it automatically casts them
 to some other form it can natively handle.  Shouldn't it do the same with
 long numbers that are above the 2**63 threshold?
