有时需要将从串口或者网络中接收的数据从字节数组转换成对应的int,float...,double等数据,有时还要考虑大小端字节序以及Swap的问题,发现在C++中需要自己写相关的转换函数,于是/写了一个函数,用于从输入的byte数组中获取指定类型的数据,目前支持int16,int32...; namespace ByteConvertTools { //
Int 带符号固定精度整数;最小范围 [-2^29..2^29-1] Int8 带符号8位整数 Int16 带符号16位整数 Int32 带符号32位整数 Int64 带符号64位整数 Integer 任意精度带符号整数;取值范围只受机器资源限制。常用 Rational 任意精度有理数。存储为两个Integer的比值 Word 固定精度无符号整数;与Int存储空间相同 Word8...
