But remember that if you add this value onto a large number and then
take off the large number the result will be zero.
(0.000,000,000,01 + 1,000,000) - 1,000,000 ==> 0
0.000,000,000,01 + (1,000,000 - 1,000,000) ==> 0.000,000,000,01
In general, operations on floating point numbers will increase their
errors.

Floating point math is good for most problems, hence why most languages
expose the abstraction.
