How to convert solidity return uint value to int and use it on frontend using Etherjs

[dev-soumyadeep]

` function fetchLoanDetails() public view returns (uint,uint){

   uint time =  block.number-addressToTime[msg.sender]; 

 return ( addressToAmt[msg.sender],time);

}`
I want to receive this return value and display it on frontend , but nothing is getting displayed . on sole the values are coming as 4072465n and 0. How to convert them into int and display them on frontend.
P.S : Used formatEther & parseEther but getting error.

All results should be a BigInt. You can use the val.toString() to get a decimal string. If it is in the range for IEEE 754 numbers, you can use JavaScript’s Number(val) without fear of rounding.

Let me know if that’s what you mean.
