I am currently working on my own currency system and am now looking for a solution to limit the decimal places in the argument to solve this problem.

Example

"/command username 4.555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555565555555555555555555555555555555555555555555555555555555555555555555555551"
