In computers, floating point real numbers are represented in binary. However, not all numeric values ​​that implement floating point can be represented exactly in binary. This is like you can't express the forum key value 1/3 as a decimal (it would be 0.3333...and so on forever).

For example:

0.1 as binary is not exact, it is only approximate. When you multiply 0.1 (as an incorrect binary representation) by 2, the result approximates to 0.2, do that (0.1*2==0, 2) returns true.

However, when you multiply 0.1 (as an incorrect binary representation) by 3, the result is not precise enough to compare with 0.3, so (0.1*3==0.3) ) returns false.
