Script Preparation code:

function getRandomInt(max) {
  return Math.floor(Math.random() * Math.floor(max));
}

var arr = [];
for(var i = 0; i < 1000; i++){
  arr.push({value:getRandomInt(100)});
}

Tests:

_.max
for (let i = 0; i < arr.length; i++) _.floor(arr[i], -2);
Math.max
for (let i = 0; i < arr.length; i++) Math.floor(arr[i] * 100) / 100;
