Good morning!
We got a question from a user:
On the following URL [redacted], there is a description of the files,
namely the size that is expressed in MB. I'd like to know if that
size is calculated using base 10 or base 2 mathematics.
Digging into the code, I find this comment for org/dspace/app/util/Util.java
/**
* Formats the file size. Examples:
*
* - 50 = 50B
* - 1024 = 1KB
* - 1,024,000 = 1MB etc
*
* The numbers are formatted using java Locales
*
* @param in The number to covnert
* @return the file size as a String
*/
public static String formatFileSize(double in) {
That's some some funky math! it divides bytes by 1,024,000 to get MB, and
1,024,000,000 to get GB. So it's neither base 2 math nor base 10, but a
combination of both.
Can anyone make a strong argument for requesting this be changed to either pure
base 10 math (divide by 1,000,000 to Mebibytes / MiB) or pure base 2 (divide by
1,048,576 to get Megabytes / MB). I prefer the latter, myself.
