how many megabytes in one gigabyte

user's unnecessary heap memory allocation mainly comes from the following aspects: High frequency New Class/container/array and so on. Research and development team remember not to open up heap memory in the update, fixupdate, or higher call frequency functions, which can cause significant damage to your project's memory and performance. to do a simple calculation, suppose that a function in your project only allocates 100B of heap memory per frame, the frame rate is 1 seconds 30

sometimes we need to show the size of a file on a Web page, or the size or number of other data. This number is often from a large span, if the unit B is likely to be bit, if 1G is up to 1073741824 of the number, this time we need to format according to size, such as less than 1K is displayed in units B, less than 1M is displayed in kilobytes, Less than 1G is displayed in megabytes, etc. ...The Format function reference is as follows:Format size Displ

When it comes to multiple-screen output, it's important to talk about AMD's "ATI Eyefinity" technology, which means that two or more display outputs run simultaneously in a separate way. From the beginning of the HD5000, the graphics card is the first to open a multiple screen of the precedent, three screen output to the current six-screen output, display output to the current GPU output, multi-screen is with its powerful function to change our lives, the following by the small computer Pepsi ne
