. 2.3.4 unsigned multiplication Take only the values represented by the low w bits, and the remaining truncation 2.3.5 Complement multiplication For unsigned and complement multiplication, the bit-level representation of the multiplication is the same as the same instruction. The low w bits of the two numbers multiplied by the unsigned and complement are always equal . Proof to see the book. 2.3.6 Multiplication constant Because the multiplication sp

Previous: Implementing RDLC Report display in MVC viewIn the last pass, Since I do not know how to instantiate the IxxxAppService.cs interface of the ABP in the aspx.cs background, I have taken the view page to store the queried data in a hidden domain of aspx, then get it in the Aspx.cs background event and assign the value to the ReportViewer control.This approach actually affects performance, the query data will be stored and converted to the page many times, and when the amount of data is la

operation, the maximum number of interchanges is the height of the tree (log n)TakeMinimum ValueOperation:In the smallest heap, take out a minimum value, of course, is to take out the first number ~ But after the tree does not have a "head"?Don't worry, we can put the last number in the head position so that the structure of the tree will not change, and the operation is simple (because it is the last number).Of course, because it is the last number, there will inevitably be a situation that do

above. Move right to erase the non-0-bit to the right of the decimal points of the result. These non-0 bits are actually positive, but because they are erased, the result subtracts the values of the non-0 bits represented by the original negative result, and the final result is rounded down rather than rounded to 0.

Product Web design and presentation (PPT) design is actually very different. Because the positioning is different, so we have to consider the user experience there are differences, product design considerations are not introduced here, and PPT speech design, due to the need to consider the clarity of the projector, with the color is to consider the point of attention, the layout of the content, The important note is to remind the presenter to follow t

how Word text becomes a PowerPoint presentation Word in a corresponding PPT in the big title, word in the two-level PPT in the body part of the first level of the title, Word level three corresponding PPT in the body part of the two level content, and so on. Generally, you can set the level up to the 3rd level. This sample screenshot, only to level 2nd, is simplified. Specific actions: Select the paragraph you want to set level, in the Outline tab

. Then, you can set the text format as needed, include font, font size, font, color and alignment of the word, and then position the cursor to the next slide, press ENTER directly to create a new slide, and press [Shift+enter] if you want to insert a blank line. After adjusting, you can quickly finish making multiple slides (Figure 2). Figure 2 Adjusting the inserted slides Finally, you can use the Outlining toolbar to make further adjustments with buttons such as upgrade, demote,

First, open the Word document, select all, and perform the copy command. Then, start PowerPoint, select Normal view, and click the Outline tab (Figure 1); If you don't have the outline and Slides tabs, the method appears on the View menu, click Normal (Restore pane), or in the lower-left corner of the window, click the Normal view (Restore pane) button. Figure 1 Simply select outline view, position the cursor over the first slide, and perform the paste command to insert all the contents

setting method of Win7 system to move multiple pictures at the same time in PPT presentation The specific methods are as follows: 1, create a new PPT, and then open a new slide; 2, in the first line of the navigation bar click "Insert"-"picture"; 3, on their own computer to find the picture they want to insert, this time need to insert more than 2 pictures, so as to achieve the ability to move the picture at the same moment
