Describe the Problem

when you call format({ units: 0, precision: 0 }) it will not return the correct value

the same happens on parseUnits function

Code Snippet

the workaround we've been doing on FE side is:


bn(amount).mul(10).format({ units: 1, precision: 0 });

which is basically multiplying by 10 first, then converting to units 1, which at the end of the day will be the same of passing units: 0

this is very overwhelming to do as we have many projects and some places can be forgotten, leading to number bugs.

Thanks for opening this @LuizAsFight just so that we are on the same page, could you share a few examples of expected results. Such as:

 expect(bn('1000000000').format({ units: 0, precision: 0 })).toEqual('1,000,000,000');

 expect(bn('1000000000').format({ units: 0, precision: 2 })).toEqual('1,000,000,000.00');

    bn('1000000000').format({
       minPrecision: 2,
     })
   ).toEqual('1,000,000,000.00');

      bn('1000000000').format({
       minPrecision: 2,
       units: 8,
     })
   ).toEqual('10.00');

This will just help us to have a clear consensus around the desired output.
