数据类型强制转换

在嵌入式领域中，对协议进行数据解析时经常需要进行字节流(小端模式)截取和数据类型相互转换

本代码封装了C语言类型和GO语言基本数据类型的相互转换

func ParseFloat

func ParseFloat(s string, bitSize int) (f float64, err error)

ParseFloat converts the string s to a floating-point number with the precision specified by bitSize: 32 for float32, or 64 for float64. When bitSize=32, the result still has type float64, but it will be convertible to float32 without changing its value.

If s is well-formed and near a valid floating point number, ParseFloat returns the nearest floating point number rounded using IEEE754 unbiased rounding.

func ParseUInt

func ParseUInt(s string, bitSize int) (u uint64, err error)

ParseUInt parse hexadecimal encoding of string to uint64 The bitSize argument specifies the integer type that the result must fit into. Bit sizes 8, 16, 32, and 64 correspond to uint8, uint16, uint32, and uint64.
