Answers

Answer 9

False. The actual output is shown in Figure 34 . This question was included topoint out that testing floating point results can be problematic. Many floating point values are simply estimates. Although this example was purposely caused tofail, a given floating point computation may not produce exactly the same results on different platforms. Therefore a test that specifies a given floatingpoint result may pass on one platform and fail on a different platform. The Python Standard Library -- 26.2 doctest -- Test interactive Python examples provides some suggestions for dealing with this issue.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
