VC++代码开发的C编译器源代码，名字就叫做Augest-3吧，可用来简单编译C扩展名的文件，代码中由于用了union，定义的变量占用4字节的内存，也就是说f和by4是共用这4字节内存的。对浮点的转化变得异常简单，union UFLOAT// 用以快速转换的自定义UFLOAT变量，一些运算

　　下面这段代码将fNum转成4字节插入到byBuf中：uf.f=f // 将要转换的浮点数放入UFLOAT变量，此时uf.by[]数组也被赋值了，因为内存是共用的。-VC++ code developed by the C compiler source code, the name of it called Augest-3 can be used to compile a simple C extensions, the code due to the use of the union, defined variables occupy 4 bytes of memory, that f and by4 are shared four bytes of memory. Converted to floating point becomes extremely simple, union UFLOAT// variables to customize UFLOAT rapid conversion of some operations

The following code will fNum turn into four byte into byBuf in: uf.f = f // will be converted into UFLOAT floating point variable, then uf.by [] array have been assigned, because the memory is shared.
