Rounding up a number to nearest multiple of 5

Question

Does anyone know how to round up a number to its nearest multiple of 5? I found an algorithm to round it to the nearest multiple of 10 but I can\'t find this one.

Answer 1

 int roundToNearestMultiple(int num, int multipleOf){
        int floorNearest = ((int) Math.floor(num * 1.0/multipleOf)) * multipleOf;
        int ceilNearest = ((int) Math.ceil(num  * 1.0/multipleOf)) * multipleOf;
        int floorNearestDiff = Math.abs(floorNearest - num);
        int ceilNearestDiff = Math.abs(ceilNearest - num);
        if(floorNearestDiff <= ceilNearestDiff) {
            return floorNearest;
        } else {
            return ceilNearest;
        } 
    }
