先按下[EXE]……

之后显示：

退出，修改参数

再次按下[EXE]……

然后：

我用四则运算方法，解决了判断二进制某一位的问题，先卖个关子……

j_0013.gif什么方法？

我原来不是发过吗？

diameter · 发表于 2010-8-24 10:04:05

你是说判断二进制某位的方法？简单，不用位运算or就可以
比如24的第4位
（24 =>BIN 11000）
第一步，24 / (2 ^（4-1）)，相当于24>>3(C语言操作符)
第二步，24 / (2 ^（4-1）)=3，判断3是否是奇数（Mod（3,2）=1）
3是奇数，所以24第三位是1.
（当位移后第一位是1时，这个数必定是奇数）

真不错！希望近期可以提供示例程序！

"想知道卡西欧图形计算器是如何显示中文的吗？"这个字符串储存在List 1中
这21个字符一共就占了12*21=252个“数字”

我不觉得多占内存？

好主意，不过对SDK编程没帮助

yzhang37 发表于 2010-8-24 11:56

why？SDK不是用C语言编程的么？
把数据存在整形数组中不行吗？

不过现在问题是绘图速度太慢（否则我就要放弃控制结构了）

yzhang37 · 发表于 2010-8-24 12:05:05

SDK速度非常快。这张图绘制出来不需要0.01秒

[Boeing 617] · 发表于 2010-8-24 12:35:10

9750GII的速度算快了。

yzhang37 发表于 2010-8-24 12:03

晕死
我的方法就是用二进制表示每一行，12个数字表示一个字符！
比如：character ”想“
const int cc_xiang []= {636,580,4092,580,1916,2756,636,0,1348,1322,2552,0};
然后用相应的算法就可以解决了！！

yzhang37 · 发表于 2010-8-24 12:55:25

你们把小看SDK的本领了。
SDK的文件格式是g1A,是图形计算器程序无法比的

你们觉得GII自然计算快吗？这就是用SDK编写的，如果用程序就慢的多了

yzhang37 · 发表于 2010-8-24 13:10:21

给大家看个图：

diameter · 发表于 2010-8-24 15:25:03

至于么？一个Int型在16位的机子下占用2字节，
比如512*512的地图，你需要512*512*2=524288个字节
而如果用512/16=32个数字表示一行，需要16384个字节
很节约！
