打乱后会以 0 开头吗？Can the shuffled number start with 0?

不会。如果打乱后第一位是 0，它会与后面第一个非 0 数字交换；只有所有数字都是 0 时才保留 0 开头。填写种子可以复现同一结果。No. If the shuffle puts a 0 first, it is swapped with the first non-zero digit after it; only an all-zero number can start with 0. Enter a seed to reproduce the same shuffle.

能处理多长的数？会丢失精度吗？How long can the number be? Is precision lost?

最多 100,000 位。数字按文本逐位处理，只是调换各位的位置，不做数值计算，所以不会丢失任何一位，例如 30 位的 123456789012345678901234567890 也能打乱。千位分隔逗号会去掉并提示；1e3 这样的指数写法和小数会报错。Up to 100,000 digits.
