奇怪的AMXX乘法????HELP

xixi

我在编写AMXX脚本时(初学),使用AMXX乘法*号时,得出的结果是负数?????
IP地址是 192.168.0.169 代码如下.

new ipcode[11], ip[30], ipta[4], iptb[4], iptc[4], iptd[4]
   new ipna, ipnb, ipnc, ipnd, ipnuma, textlen
   get_user_ip(param[0], ip, 16, 1)
   replace(ip, 16, ".", " ")
   replace(ip, 16, ".", " ")
   replace(ip, 16, ".", " ")
   replace(ip, 16, ".", " ")
   parse(ip, ipta, 3, iptb, 3, iptc, 3, iptd, 3)
   ipna = strtonum(ipta)
   ipnb = strtonum(iptb)
   ipnc = strtonum(iptc)
   ipnd = strtonum(iptd)
   ipnuma = (ipna*256*256*256)+(ipnb*256*256)+(ipnc*256)+ipnd


   client_print(0,print_chat,"ipna: %i ipnb: %i ipnc: %i ipnd: %i ipnuma: %i ", ipna, ipnb, ipnc, ipnd, ipnuma)

结果 ipnuma 的值是 -1062731607 ?!

我用PHP计算的代码如下:

[PHP]
$Ip="192.168.0.169";
$array=explode('.',$Ip);
$Int=($array[0] * 256*256*256) + ($array[1]*256*256) + ($array[2]*256) + $array[3];
echo $Int;
[/PHP]

PHP计算得出的值是 3232235689

AMXX算出来的怎么和PHP差那么多呀,大家帮帮我.看我的AMXX代码要怎么样写才能得出PHP计算的那个值呀???????

xixi

AMXX的数值变量长度不能超过10位.一超过就溢出呀.
例:

3657433088

在AMXX里显出来的是

-637534208

smartsl

一个256就是0x100，4个就是0x100000000，在32位机器上正好够用。不过SMALL语言里面似乎只有signed类型，所以范围就是
-2147483648~2147483647。

不知道楼主想计算这个干什么？一定可以换一种方法解决。

xixi

想用QQ的IP地址文件QQWRY.DAT的数据呀.
要用第一步就是要把IP转换出来呀.

第一个计算都不行,我倒呀...

顶 :cry2:  :cry2:  :cry2:  :cry2:

helloworld

client_print(0,print_chat,"ipna: %i ipnb: %i ipnc: %i ipnd: %i ipnuma: %i ", ipna, ipnb, ipnc, ipnd, ipnuma)

换成
client_print(0,print_chat,"ipna: %d ipnb: %d ipnc: %d ipnd: %d ipnuma: %d ", ipna, ipnb, ipnc, ipnd, ipnuma)

xixi

不行呀. :10:
