Hey!
I want to just post an additional simple solution to a problem that I tried to understand and fix which is visualizing a float value (UI, HUD etc) meaning that when you want to show 61.4 you get 61.399999 etc.
There is a node https://docs.unrealengine.com/latest/INT/BlueprintAPI/Utilities/Text/ToText_float/index.html which works perfectly. The only thing that is necessary to change is the “Maximum fractional digits”, for example if you want to get 61.4 from 61.39999 put 2 there.
I wrote this because today I lost all day trying to find some solution and from all the already listed solutions, this one was missing.
Cheers.
