Calculation error

[tilkinsc]

1 / 9 * 9 == 0.9999999

It should actually be this

1 / 9 * 9 == 1

can i fix it

[yuzheng14]

It is practically 0.9999999.
Because the calculator calculator the 1/9 first, then it multiply the result of 1/9 and 9, then it get 0.9999999999

It is practically 0.9999999. Because the calculator calculator the 1/9 first, then it multiply the result of 1/9 and 9, then it get 0.9999999999

Huh?
Also, its widely accepted that this isn't a correct calculation and its not.
f(x) = x / 9 * 9
f(f(f(f(f(1))))) != 1

It's gradual depreciation

But, it's divide into two steps, and convert to float, so that it will lose a little bit accuracy among the process.

Its not an int to float conversion its all doubles and stays doubles.
