Better solution:
This is the most accurate and actually corrects a mistake posted by the top rated answer in this post. The “AsCurrency” node is deprecated, so using the “ToText (float)” node is a good alternative. Also, “Use Grouping” needs to be unchecked, otherwise a value such as “2156466.5” will get rounded to “2.0” (Strange, huh?)
