Human Decimal Formatter
This module provides a decimal field formatter that displays only the significant digits of a number, cleaning up trailing zeros. For example, 3.00 would display as 3, while 3.23 would remain as 3.23.
About
A tiny module that provides a simple decimal field formatter that displays decimal digits only if exist (because humans are not computersTM).
For example 3.00 will render as 3 (no digital digits) but 3.23 will render as 3.23 etc.
Initially I found it helpful to propose this formatter on core but until this happens it would be better to add this here as a separate module and get feedback from the community.
Scaffolding was made with Drupal Console.
Usage
Just install and use the formatter for any decimal number field you want to. There are no special settings for the formatter.
