Is it possible to use BigNumber together with Math.js in BOS?

I’ve been trying to use one of the Math library functions found within BOS but it doesn’t seem to exist.
The function I tried to use is Math.bigbumber().
This function is important since I need it to be able to have greater precision for my calculations in DeFi

I’m working on a series of components focused on the DeFi environment within BOS, I have been working with the Math library that is implemented using functions such as ceil, floor, exp and others to be able to perform the necessary calculations in the process to add liquidity , I encountered the problem that at some point in the calculations the result is rounded to a number of decimal places, this is a problem since I cannot be precise in the liquidity calculations, causing it to not enter the correct cases according to the formulas .

To solve the problem I had planned to use big numbers for the calculations, but when trying to use the function to declare bignumbers within math I realized that it was not available since it did not exist and gave a code error.

Is there a way to use big number within BOS to obtain greater precision in the calculations and for the formulas to work correctly?
