BigInteger.remainder介绍

[英]Returns a BigInteger whose value is this % divisor. Regarding signs this methods has the same behavior as the % operator on ints: the sign of the remainder is the same as the sign of this.
[中]返回一个BigInteger，其值为该%除数。关于符号，此方法与ints上的%运算符具有相同的行为：余数的符号与此的符号相同。

@Override
public boolean contains(BigInteger value) {
  if (value == null || value.compareTo(from) < 0 || value.compareTo(to) >= 0) {
    return false;
  }
  return value.subtract(from).remainder(incrementUnit).compareTo(BigInteger.ZERO) == 0;
}
