size of attached files in unit bytes is shown with decimals

[meigelb]

Overview

The size of a file attached to an entry is shown in as a separate column in a list. For files with size below 1024 bytes, the size is shown in smallest unit "B" (bytes) but also displays two decimals. This is a bit misleading, since for file sizes no fractions of size exist and, hence, should not be displayed. For larger units, such as kilobytes, the decimals should be shown.
The issue is shown in the following screenshot and marked with the red box:

Steps to Reproduce

1. add a new entry to your database
2. to this entry, add an attachment of size smaller than 1024 Bytes
3. in the GUI, besides the "Name" also the "Size" of the attached file is shown
4. the size is given in unit bytes denoted by "B" but shows two decimals, see screenshot above

Expected Behavior

The size of the file in bytes should be shown as integer without decimals. Only files larger than 1024 bytes, should show decimals if presented in their corresponding unit, such as kilobytes.

Actual Behavior

The size of files smaller than 1024 bytes is shown in bytes but with two decimals. But no fractions of bytes exist when it comes to file sizes.

Context

The issue occurs independent of user-selected language.
