如何去掉小数点后的零？

def remove_trailing_zeros(number):
    return str(number).rstrip('0').rstrip('.') if '.' in str(number) else str(number)

# 示例
number = 123.45000
result = remove_trailing_zeros(number)
print(result)  # 输出: 123.45

function removeTrailingZeros(number) {
    return number.toString().replace(/(\.\d*?[1-9])0+$|\.0*$/, '$1');
}

// 示例
let number = 123.45000;
let result = removeTrailingZeros(number);
console.log(result);  // 输出: 123.45

public static String removeTrailingZeros(double number) {
    return new BigDecimal(number).stripTrailingZeros().toPlainString();
}

// 示例
double number = 123.45000;
String result = removeTrailingZeros(number);
System.out.println(result);  // 输出: 123.45
