that $200.00 is harder to alter

Luckily, though, it is common to use commas to separate groups of three digits: $200,000.00 But this means a change of a factor 1000 which might be less useful than the original 20$ -> 320$ example.

That depends on locale other countrys do not use commas as separators in the same way
