Convert Hex integer to number (chainlink)

Question

I have a smart contract that returns the price of ETH using Chainlink. When i call getPrice() from geth i get a very large HEX number. How can i get the decimal number out of the hex value?

constructor (address _manager) ReentrancyGuard() {
        manager = _manager;

        priceFeed = AggregatorV3Interface(ETH_USD_RINKENBY);
    }

function getPrice() public view returns (int) 
{        
    (
        uint80 roundID,
        int price,
        uint startedAt,
        uint timeStamp,
        uint80 answeredInRound
    ) = priceFeed.latestRoundData();

    //uint8 decimals = priceFeed.decimals();

    return price;
}

returned values example

"0xfd918bdff54b7c2d1b639fe258ea80d8f00c68e096cce9cef69b42ff6b19522d" "0x480f2a54bec768ccc4e97983b62925d62075fe374d2daaadfd9d686f6a2757a4" "0x0d30772eaf09ac3ceb1e2b80e74757ae10db37a33d9aa0cdb8df3eb228981ae5" "0xfb0d591bca5c552ff4ecea8c5ff52da7f7df7925ec5a1bc95ecf77d8ddd3b9d1" "0x0d0abf0bdeb72dd3de217d6663993c0704fe20bb124ca1caad3ba74543a23894" "0xfd4f9d6f754414702a7c30cc9eda7c89472c0dea1f5881557687eafef3317db4" "0xdb8102933cff94ee14c46d58af60e534c8eb1da3f5d1c1f9a8b18b7dacb65e56" "0xdc8b57ffcc0c338b912f21241fd1f4451f079dd3229ad529d798eea2b3d29350

Using javascript you can use parseInt! Not only does it take regular string numbers, it also takes hex strings!

You can read about it here.

The interface is parseInt(string, radix) The second argument is the "radix" - which is a math term for essentially "base"

For your example above (taking the first hex string) parseInt('0xfd918bdff54b7c2d1b639fe258ea80d8f00c68e096cce9cef69b42ff6b19522d', 16)
