解决浮点数：

console.log(Math.formatFloat(6.8-0.9, 2));
console.log(Math.formatFloat(6.8-0.8, 2));
console.log(Math.formatFloat(6.8-0.4, 2));
console.log(Math.formatFloat(6.8-0.3, 2));
/ / 5.9     6     6.4     6.5

Math.formatFloat = function (f, digit) {
  const m = Math.pow(10, digit);
  return Math.round(f * m) / m;
}
