[New-bugs-announce] [issue35188] something confused about numpy.arange

[xiyunlong]

New submission from xiyunlong <xyl123 at sjtu.edu.cn>:

when I use:print(np.arange(1,2.2,0.2))
I got: 
1.0
1.2
1.4
1.5999999999999999
1.7999999999999998
1.9999999999999998
2.1999999999999997
could any one tell me why it's not 1.0,1.2,1.4,1.6,1.8,2.0?
Many thanks!
