| *{{GVI|arma 3|1.16}} Please note the difference between [[for forspec]] and [[for do]], [[for forspec]] detects Boolean in each scope while [[for do]] doesn’t. e.g.

| *Never try to tell a decimal number via binary number in a loop; otherwise the loop will be infinite:
| |
| <code>
| |
| '''for''' [{_a = 0},{_a != 1},{_a = _a + 0.1}] [[do]] {}; //an infinite loop; _a will never be 1 so the scope will always be true.
| |
| </code>
| |
| Any binary number behind the decimal point is always the sum of 1/2, 1/4, 1/8, 1/16 etc. so decimal number with odd denominator like 1/3 or 1/10 cannot be exactly equal to each other.
| |
| *Avoid too large factorial multiply which may loose the leading indicator in result. And 12 is the biggest accessable factor in this example.
| |
| <code>'''for''' [{_a = 2; _b = 1;},{_a < 100},{_a = _a + 1}] [[do]] {_b = _b * _a}; // _b = 1.#INF</code>
