Hi Alex,
Thanks for checking into it!
The backend services page automatically adds ".00" or cents to the number. For example, if you enter "5000" and save it, it will show up as "5000.00" after the save.
For Japanese yen, Korean won, and others - a decimal with cents added is not used.
I was hoping to just add something like Math.trunc() to the variable cut the decimal out, but can't seem to be able to affect the output.
