divide

问题 I know and understand the result. For example: <br> 7 (decimal) = 00000111 (binary) <br> and 7 >> 2 = 00000001 (binary) <br> 00000001 (binary) is same as 7 / 4 = 1 <br> So 7 >> 2 = 7 / 4 <br> <br> But I'd like to know how this logic is created. Can anyone elaborate on this logic ? (Maybe it's just popped up in a genius head ?) And is there any other similar logics like this ? 回答1: It didn't "pop-up" in a genius' head. Right shifting binary numbers would divide a number by 2 and left shifting

问题 Hi I am trying to split the values in a (y2) list into (inv) amount of parts. x = [0,100,200,300,400,500,600,700,800,900,1000,1100] y2 = [58,55,49,12,6,5,4,4.5,35,48,56,58] interval = 5 inv = (x[0] + x[1])/interval I will like to split y2 into inv parts so my answer should be: [58 57.85 57.7 57.55 57.4 57.25 57.1 56.95 56.8 56.65 56.5 56.35 56.2 56.05 55.9 55.75 55.6 55.45 55.3 55.15 55...…….49...…………..12...….6 ………...5...……..] I will like to mention that inv will always be (x[0] + x[1])

问题 Hey all, first post and a noob in Android programming, but willing to learn! Basically I've taken the Google sample of a tab layout from here I found that method to be very easy to create tabs with text within each tab, but I'm trying to make it so that when a tab is selected, I want the text listed below to be separated by a dividing line. So that a line is dividing between each paragraph, however I'm having trouble doing this. This is what I have so far: main.xml: <?xml version="1.0"

问题 I am trying to divide two var in bash, this is what I've got: var1=3; var2=4; echo ($var1/$var2) I always get a syntax error. Does anyone knows what's wrong? 回答1: shell parsing is useful only for integer division: var1=8 var2=4 echo $((var1 / var2)) output: 2 instead your example: var1=3 var2=4 echo $((var1 / var2)) ouput: 0 it's better to use bc: echo "scale=2 ; $var1 / $var2" | bc output: .75 scale is the precision required 回答2: There are two possible answers here. To perform integer

问题 Web app coded in PHP with a MySQL database. I have a system which calculates different costs for a number of people when splitting a cost. For example Person A buys something for 10 and Persons B, C, and D should split the cost. The system should therefor register a positive record for person A of 10 and negative records of 10/3 for B, C and D. However, when this is done; B, C and D all have -3.33 after rounding. Which of course doesn't add up to the total of 10. What's the best way of going
