Wouldn't it be better to use arbitrary precision arithmetic instead of floating point arithmetic?

[Sl-L]

Currently, setting precision to 16 causes operations like 7 / 5 or 13 / 5 to show the inaccuracies of floating point arithmetic.
I suggest it would be better to either set the maximum precision at 15 decimal digits (which is how google's calculator works around this) or move away from floating point arithmetic to arbitrary precision arithmetic (like how windows calculator handle this since windows 98)

Try
Settings -> Calculator -> Precision

Please try reading again. I know that it gets "fixed" by lowering the decimal precision, I'm questioning why the app allows 16 decimals when doubles only have 15 decimals of stable precision
