Status: RESOLVED DUPLICATE of bug 260741

(Toolkit :: Downloads API, defect)

Description

[Jorg Floren]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.10) Gecko/20050716 Firefox/1.0.6
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.10) Gecko/20050716 Firefox/1.0.6

When (for example) downloading winamp (5.09 Full version) the website states the
size to be 4.6Mb, the file in reality is 4.93Mb. The FireFox Download Manager
indicates the file size to be 5.1Mb. The size of the file in reality is
5.176.904 bytes. The error is in the calculation of Mb. The download manager
apperantly divides the number of bytes by 1.000.000 or even truncates the number
instead of dividing it by (1024)^2 

Reproducible: Always

Steps to Reproduce:
1. Download any file bigger then one Megabyte
2. Check the size the Download Manager indicates
3. Check the size on disk of the downloaded file

Actual Results:  
1. Download starts
2. Manager reports a size of 5.1 Megabyte
3. File size on disk is 4.93 Megabyte

Expected Results:  
The download manager should have reported the filesize to be 4.93 Megabyte
