要求如下 各位帮忙下 ,就是电话号码后4位乘以80,然后把整数去掉,小数点后面的数字再除以80能得到整数,但我想反过来做,这样就可以得到最原始的4位数字,不知道怎样计算 谢谢各位了 好的话我加分
我的意思是比如1234除以80=15.425,然后把整数去掉就=0.425 再拿这个0.425乘以80=34 我的想法是能不能调换过来 就是把34直接换算成 1234呢?
难道就没有任何办法了么?

At one point along an open highway,I came to a crossroads with a traffic light.I was alone on the road by now,but when I drove up to the light,it turned red,and I braked to a halt.I look left,right,and behind me.Nothing,① a car,no suggestion of headlights,but there I sat,waiting the light to change,the only human being for at least a mile in any direction.
I started wondering why I refused to run the light.I was not afraid of being caught by the police,because there was obviously no cop anywhere around and ② certainly would have been no danger in going through it.Much later that night,the ③ question of why I’d stopped for that light came back to me.I think I stopped because it’s part of a contract (合同) we all have with each other.It’s not only the law,but it’s an agreement we have,and we trust each other to honor ④ ；we don’t go through red lights.Like most of us,I’m more ready to be stopped from doing something bad by the social agreement that disapproves of it ⑤ by any law against it.

I don't know if this is something somebody else may have thought of and posted.It seems like something that someone should have thought of long ago.I've been so busy lately that I didn't have time to check for myself.
It's from Alizée's performance at the Eiffel Tower where she sings J'ai pas vingt ans.The original video is a little over 7 minutes long.She sings during the first 4 minutes,then during the last 3,she is standing on stage with the emcee,sometimes talking to her.During these last 3 minutes,there are some incredibly beautiful clips of Alizée.
I often watch the singing part,but seldom watch the last 3 minutes because I grow weary of hearing the other woman jabbering,so I figured I'd take those clips from the last 3 minutes and splice them into the first 4.It's not a dramatic difference,but I like it and figured I go ahead in post it in case anyone else did.

I'm terribly disappointed you guys don't know the history of this video.The occassion was to celebrate the completion of a series of strobe lights all up and down the tower.They had put some up temporarily a couple of years before and it was such a big success that they decided to put a permanent set up.The countdown was for when they were going to turn on these lights for the first time.There were reportedly over 350.000 people in attendance.
In december of 2007,I went to Paris to get Alizée's autograph when she released her Psych album.I knew something had been done with the lights on the tower due to this video,but I had no idea what.The night that I got Alizeée's autograph,afterwardsI decided to walk over towards the tower,which I hadn't seen to this point,to do some sight seeing.
I was walking down a hill when I saw the end of a street that had a series of red Christmas lights on all the trees that lined it.I walked down to get a closer look.When I turned the corner,I saw up between these trees with the beautiful red Christmas lights,was the Eiffel tower with all these strobe lights flashing off and on.What an awesome sight.Unbelievable!It turns out that they turn on these lights at night at the top of each hour for 10 minutes and to have turned that corner when these lights were on was just a stroke of incredible luck.I'll never forget it.
