Description: 1. #!/usr/bin/perl 是系统中Perl所在的路径
2. Perl程序并不需要变量声明的部分，所有变量可以直接使用。但是如果想提前声明也可以。
3. 换行符 \n
最好在每一行输出的信息的末尾加上换行符，使得程序执行完后SHELL的提示符出现在
新的一行的开始，而不是在输出内容的后面。
4. 反引号`` 运行一个外部命令，使用一对反引号来调用。反引号和单引号不同，注意别搞混了。
5. perldoc -u -f atan2 >d:/temp
可以将命令执行结果和输出内容导入别的文件。
6. 标量 SCALAR 用于称呼单件事物，是Perl中最简单的数据类型。
类似于别的语言的常量和变量
7. 双精度浮点数
所有的数字都以这种形式存储和参加运算，不区分小数，整数或者浮点数等。
但是在程序代码中书写时还是可以用各自的直接量来表示的。
例如：浮点数直接量，整数直接量等
8. 运算符

Description: CORDIC For Dummies
CORDIC is a method of calculating a math function using much simpler math operations in a loop called a Binary
Search. Most commonly CORDIC is used to calculate ATAN2 (Angle), and Hypotenuse (Distance) of a point.
CORDIC can also be used to calculate other math functions like SIN and COS.
