This is a PHP program to get the size of the file and the file according to the size of the file display GB,MB,KB code code is very smart code, the code is as follows: function Sizecount ($filesize) { if ($filesize >= 1073741824) { $filesize = Round ($filesize/1073741824 * 100)/100. ' GB '; } elseif ($filesize >= 1048576) { $filesize = Round ($filesize/1048576 * 100)/100. '

In a file-processing system, it is easy to get the size out of some system's own method, the problem is that the size is often just a byte B.If you want to convert this byte number to a KB, MB, GB final rendering to the user, it involves the arithmetic operation of dividing and taking the remainder.Here's how:public static String getprintsize (long size) {///If the number of bytes is less than 1024, it is d

For example, when we refer to "data transfer speed" and "hard disk storage space", kilobytes represent 1000 (103), and when it comes to memory or CPU cache capacity, kilobytes represent 1024 (210) because they are stored here by byte-code address. In practical applications, we often need to convert bytecode to KB, MB, GB, and so on, where we use JavaScript to convert bytecode: The code is as f

Exposure to computers all day, inevitably with a variety of measurement units to deal with, especially data, but you know bit, Byte, KB, GB, TB and so on all means how much data? Have you heard of EB, ZB, YB? Bit (bit) is the initials of binary digit, the unit that measures information, and the smallest unit that represents the amount of content, only 0 or 12 binary states. 8 bits make up a byte (byte), can hold an English character, and a Chinese ch

The code is as follows Copy Code function Sizecount ($filesize) {if ($filesize >= 1073741824) {$filesize = Round ($filesize/1073741824 * 100)/100. ' GB ';} elseif ($filesize >= 1048576) {$filesize = Round ($filesize/1048576 * 100)/100. ' MB ';} elseif ($filesize >= 1024) {$filesize = Round ($filesize/1024 * 100)/100.

In the computer newspaper, I saw that ABN Amro's 20 data centers have about 7PB of disk and more than 20PB of tape storage, and the annual 50%~70% growth of storage, So I want to see how big the PB is, and calculate the 27PB size of the hard disk about 400,000 80. 1Byte = 8 Bit (0,1) 1 KB = 1,024 Bytes (size of a shortcut) 1 MB = 1,024 KB = 1,048,576 Bytes (size

Using the FileSize () function command to achieve file size statistics, requires: 1, in GB, MB, KB, b in one output; 2. The order of magnitude must be greater than 1 and less than 1024, and two decimal places are reserved; Commenced construction: Copy CodeThe code is as follows: $len = FileSize ("1.RMVB"); $i = 4; while ($i) { if ($out = $len/pow (1024x768, $i)) >1.0| | $i ==1) { Switch ($i) { Case 4: {pri

The JS code is as follows:var size = ' 8164674 '; function bytestosize (bytes) { ifreturn ' 0 B '; var // or 1024x768 sizes = [' B ', ' KB ', ' MB ', ' GB ', ' TB ', ' PB ', ' EB ', ' ZB ', ' YB '], = Math.floor (Math.log (bytes)/ Math.lo G (k)); return (Bytes/math.pow (k, i)). Toprecision (3) + "+ Sizes[i];} Console.log (Bytestosize (parseint (size)));SummarizeThe next two storage

I learned the fread reading command and used the filesize function to compile the statistics file size function. I learned the fread reading command and used the filesize function to compile the statistics file size function. Use the filesize () function command to calculate the file size. The value 1 must be an output of GB, MB, KB, and B. 2. the order of magnitude must be greater than 1 and less than

Php obtains the file size and converts the file size to gb, mb, and kb. this code uses the php program to obtain the file size and displays the file size as gb, mb, the code of kb code is very intelligent. the code is as follows: Function sizecount ($ filesize ){ If ($ filesize> = 1073741824 ){ $ Filesize = round

Use the filesize () function command to calculate the file size. The value 1 must be an output of GB, MB, KB, and B. 2. the order of magnitude must be greater than 1 and less than 1024, and two decimal places must be retained; Start: Copy codeThe Code is as follows: $ len = filesize ("1. rmvb "); $ I = 4; While ($ I ){ If ($ out = $ len/pow (1024, $ I)> 1.0 | $ I = 1 ){ Switch ($ I ){ Case 4: {printf

PHP implements the original method of converting Byte to KB, MB, GB, and TB. This example describes how to convert the number of bytes in PHP to KB, MB, GB, or TB. We will share this with you for your reference. The details are as follows: The previous section describes how to convert the number of bytes in java to

Use the FileSize () function command to implement statistics for file size, requiring: 1, one output in GB, MB, KB, B, 2. The order of magnitude must be greater than 1 less than 1024 and retain two decimal places; Commencement of construction: Copy Code code as follows: $len = FileSize ("1.RMVB"); $i = 4; while ($i) { if ($out = $len/pow (1024, $i) >1.0| | $i ==1) { Switch ($i) { C

We often hear about who drives the broadband is 4M or 10M or 20M and so on. So this is the same as what we call "how much MB/s" and "How many kb/s"?In fact, this is not a concept.Broadband operators in the broadband, such as 4M, is actually said 4M bit/s, that is, bits per second.And what we call the download speed is b/s, that is, bytes per second.Remember two relationships: 1b/s = 8 b/s;1 M =1024k.So 1M o
