[removed] Round up to the next multiple of 5

Question

I need a utility function that takes in an integer value (ranging from 2 to 5 digits in length) that rounds up to the next multiple of 5 instead of the

Answer 1

// round with precision

var round = function (value, precision) {
    return Math.round(value * Math.pow(10, precision)) / Math.pow(10, precision);
};

// round to 5 with precision

var round5 = (value, precision) => {
    return round(value * 2, precision) / 2;
}

Answer 2

voici 2 solutions possibles :
y= (x % 10==0) ? x : x-x%5 +5; //......... 15 => 20 ; 37 => 40 ;  41 => 45 ; 20 => 20 ; 

z= (x % 5==0) ? x : x-x%5 +5;  //......... 15 => 15 ; 37 => 40 ;  41 => 45 ; 20 => 20 ;
