js 0.1+0.2 !== 0.3 简单解决方案

export const round = number => {
  const getFloat = number.toString().split(".");
  if (getFloat.length === 1) {
    return number;
  }
  const floatLength = getFloat[1].length;
  if (floatLength > 6) {
    return Math.round(number.toFixed(2) * 100) / 100;
  }
  return number;
};
