/********************************************************************************
*类名:myMath.Scale
*功能:实现不同进制之间的转换
*用法:myTest = new Scale();
* bin = 11111;
* trace(myTest.binTOoct(bin));

示例：

import myMath.Scale;
myTest = new Scale();
bin = 11111;
trace("原始数:"+bin);
trace("二进制向八进制转换:"+myTest.binTOoct(bin));
trace("二进制向十进制转换:"+myTest.binTOdec(bin));
trace("二进制向十六进制转换:"+myTest.binTOhex(bin));
oct = 777111;
trace("原始数:"+oct);
trace("八进制向二进制转换:"+myTest.octTObin(oct));
trace("八进制向十进制转换:"+myTest.octTOdec(oct));
trace("八进制向十六进制转换:"+myTest.octTOhex(oct));
dec = 100;
trace("原始数:"+dec);
trace("十进制向二进制转换:"+myTest.decTObin(dec));
trace("十进制向八进制转换:"+myTest.decTOoct(dec));
trace("十进制向十六进制转换:"+myTest.decTOhex(dec));
//十六进制应为字符串
hex = "ffff";
trace("原始数:"+hex);
trace("十六进制向二进制转换:"+myTest.hexTObin(hex));
trace("十六进制向八进制转换:"+myTest.hexTOoct(hex));
trace("十六进制向十进制转换:"+myTest.hexTOdec(hex));
//恶搞一下
trace("恶搞一下...");
trace(myTest.decTObin(myTest.hexTOdec("ffFF")));
trace(myTest.decTOhex(myTest.hexTOdec("ffFF")));; 0
