 Reporter:  hongdog       |       Owner:  somebody
     Type:  defect        |      Status:  new     
 Priority:  normal        |   Milestone:  2.0.0   
Component:  Other         |     Version:  1.3.0   
 Keywords:  arange 1.3.0  |  
--------------------------+-------------------------------------------------
 Using spyder with python 2.6.2 and numpy 1.3.0 on Windows XP, I found the
 following problem.

 --------------
 In [31]: arange(12.5,13,0.1)
 Out[31]: array([ 12.5,  12.6,  12.7,  12.8,  12.9]) # "13.0" is not here

 In [32]: arange(12.6,13,0.1)
 Out[32]: array([ 12.6,  12.7,  12.8,  12.9,  13. ]) # "13.0" is here
 --------------

 As shown, the "end 13.0" is not shown in 1st array, which is correct based
 on the document, but shown in 2nd array.
