Tests:

  • pow

     
    var tmp = Math.round((Math.random()*100000000));
    var i = 8;
    var tmp = tmp/Math.pow(10, i);

  • **

     
    var tmp = Math.round((Math.random()*100000000));
    var i = 8;
    var tmp = tmp/(10 ** i);

  • *

     
    var tmp = Math.round((Math.random()*100000000));
    var i = 8;
    while(i-- > 0){
                tmp = tmp/10;
    }

  • e to number

     
    var tmp = Math.round((Math.random()*100000000));
    var i = 8;
    var tmp = tmp/Number(10+'e'+i);
