Possibility of working with values greater than MAX_SAFE_INTEGER

[DOUGLASMD1]

Is there a possibility to work with the entry of coins above MAX_SAFE_INTEGER?

For both decimal and integer values?

For example: 9.999.999.999.999.999.999.999,99

I have a feature in my project that should support up to 24 digits
