我有一个简单的代码： -
for (var a:int=1; a<10000; a++) {
if (a%3==0 && a&5==0){
trace (a);
}
}
运行时没有任何内容。
答案 0 :(得分：1)
好的，现在您的问题已经清楚解释了。所以+1 我真的不明白你为什么要用＆amp; Bitwise AND！
for(var n:int=1; n<=100; n ++){
if (n%3==0 && n%5==0){
trace(n + " is divisible by 3 AND 5");
}
}
输出：
15 is divisible by 3 AND 5
30 is divisible by 3 AND 5
45 is divisible by 3 AND 5
60 is divisible by 3 AND 5
75 is divisible by 3 AND 5
90 is divisible by 3 AND 5
显然不是
// if (a%3==0 && a&5==0)...
所以，在你的情况下：
for (var nmb:int=1; nmb<10000; nmb++) {
if (nmb%3==0 && nmb%5==0){
trace (nmb + " is divisible by 3 AND 5");
}
}

只需编辑您的问题......
答案 1 :(得分：0)
你的两个条件永远不会匹配。
您熟悉“按位AND运算符”吗？
所以这不是一个简单的代码。 ：）
查看参考资料以获取更多详细信息：Bitwise AND
我不知道你想做什么，目前还不清楚...... 请更具体一点！
这样可行（％3总是“0”，所以你不必处理模数）：
for (var b:int=0; b<=30; b+=3) {
//trace ("Boolean("+ b + "&5) = " + Boolean(b&5));
// If You want to test the Boolean values...
if (b%3==0 && Boolean(b&5)==false){
trace (b);
}
}
与：
相同for (var b:int=0; b<=30; b+=3) {
//trace ("Boolean("+ b + "&5) = " + Boolean(b&5));
// If You want to test the Boolean values...
if (Boolean(b&5)==false){
trace (b);
}
}
由于模数总是等于“0”！
输出：
b = 0
b = 18
b = 24
或者：
for (var b:int=3; b<=30; b+=3) {
//trace ("Boolean("+ b + "&5) = " + Boolean(b&5));
if (b%3==0 && Boolean(b&5)==false){
trace (" b = " + b);
}
}
输出：
b = 18
b = 24
b＆amp; 5无法匹配％3 == 0，因为它是二进制检查。
所以没有输出=＆gt;没有结果显示。
var insert:Number = 13;
var update:Number = 11;
trace(insert & update); // 9 (or 1001 binary)
这就是你的循环无法给出任何结果的原因。所以没有输出！
另请尝试：
for (var a:int=0; a<=30; a+=3) {
trace ('parseInt(String(\"' + a + '\"),2) = ' + parseInt(a.toString(),2));
trace(a + "&5" + " = " + (a&5));
}
输出：
parseInt(String("0"),2) = 0
0&5 = 0
parseInt(String("3"),2) = NaN
3&5 = 1
parseInt(String("6"),2) = NaN
6&5 = 4
parseInt(String("9"),2) = NaN
9&5 = 1
parseInt(String("12"),2) = 1
12&5 = 4
parseInt(String("15"),2) = 1
15&5 = 5
parseInt(String("18"),2) = 1
18&5 = 0
parseInt(String("21"),2) = NaN
21&5 = 5
parseInt(String("24"),2) = NaN
24&5 = 0
parseInt(String("27"),2) = NaN
27&5 = 1
parseInt(String("30"),2) = NaN
30&5 = 4
也测试一下：
for(var t:int=3; t<=30; t +=3){
trace ('parseInt(String(\"' + t + '\"),2) = ' + parseInt(t.toString(),2));
trace(t + "&5" + " = " + (t&5));
}
输出：
parseInt(String("3"),2) = NaN
3&5 = 1
parseInt(String("6"),2) = NaN
6&5 = 4
parseInt(String("9"),2) = NaN
9&5 = 1
parseInt(String("12"),2) = 1
12&5 = 4
parseInt(String("15"),2) = 1
15&5 = 5
parseInt(String("18"),2) = 1
18&5 = 0
parseInt(String("21"),2) = NaN
21&5 = 5
parseInt(String("24"),2) = NaN
24&5 = 0
parseInt(String("27"),2) = NaN
27&5 = 1
parseInt(String("30"),2) = NaN
30&5 = 4
NaN永远不会给你var％3 == 0;）
最好的问候。
尼古拉斯。
