How to round float to x decimal places?

Thanks, I missed the whole “failable functions” part.

Round() only rounds to a whole number, what I need is to round to 3 decimal places.

Can you please give me an example?
Value = 6.456123456
and my desired output is 6.456 as float or as string (“6.456”).

Below is my attempt, when I divide the integer with 1000, and I get a rational type, and there is no way to convert a rational to either float or string.

        var myFloatNumber : float = 6.456123456 * 1000.0
        var myIntNumber : int = 0
        var myFinalNumber : string = ""

        if (Value := Round[myFloatNumber]):
           set myIntNumber = Value      

        if (Value : rational = myIntNumber / 1000):
            set myFinalNumber = ToString(Value)
            
        
        Print(myFinalNumber)
