说明：  VB串口通信中经常会遇到10进制浮点数转为多字节Byte数据类型的情况，以及在接收后需转为10进制浮点数需求。 VB有专门的API函数CopyMemory能处理2-10进制浮点数转换和10-2进制浮点数转换。 下列代码演示了10进制Single（单精度浮点型转为16进制字符显示的浮点数和其相反运算：
(VB serial communication often encounter decimal floating-point to multi-byte Byte data type, as well as after reception needs to be converted to decimal floating-point number. VB has a special API function CopyMemory can handle binary floating-point conversion and 10-2 2-10 hex floating-point conversion. The following code demonstrates decimal Single (single-precision floating-point into a hexadecimal character display of floating point operations and its opposite:)
