Java BigDecimal的负数到二进制形式

import java.math.BigDecimal;
import java.math.BigInteger;

public class BigDecimalToBinary {
    public static void main(String[] args) {
        BigDecimal number = new BigDecimal("-10.5");

        // Step 1: Get the absolute value
        BigDecimal absNumber = number.abs();

        // Step 2: Convert absolute value to binary
        BigInteger binary = absNumber.toBigInteger().abs();

        // Step 3: Invert each bit if the original number is negative
        if (number.signum() == -1) {
            char[] bits = binary.toString(2).toCharArray();
            for (int i = 0; i < bits.length; i++) {
                bits[i] = (bits[i] == '0') ? '1' : '0';
            }
            binary = new BigInteger(String.valueOf(bits), 2);
        }

        // Step 4: Convert to two's complement form
        binary = binary.add(BigInteger.ONE);

        System.out.println("Binary representation: " + binary.toString(2));
    }
