js 十进制转换为二进制

let decimalNumber = 10;
let binaryString = decimalNumber.toString(2);
console.log(binaryString); // 输出 "1010"

function decimalToBinary(decimal) {
    let binary = '';
    while (decimal > 0) {
        binary = (decimal & 1) + binary;
        decimal >>= 1;
    }
    return binary || '0';
}

console.log(decimalToBinary(10)); // 输出 "1010"

function decimalToBinaryRecursive(decimal) {
    if (decimal === 0) return '0';
    if (decimal === 1) return '1';
    return decimalToBinaryRecursive(Math.floor(decimal / 2)) + (decimal % 2);
}

console.log(decimalToBinaryRecursive(10)); // 输出 "1010"

let bigDecimal = BigInt(12345678901234567890);
let bigBinary = bigDecimal.toString(2);
console.log(bigBinary);

let negativeDecimal = -10;
let negativeBinary = (negativeDecimal >>> 0).toString(2);
console.log(negativeBinary); // 输出 "11111111111111111111111111110110"
