1. If you need the result as byte array, you should pass it directly without changing it to a string, then change it back to bytes. In your example the (f.e.: 0x31 = 1) is the ASCII codes. In that case to convert a string (of hex values) to ASCII values use: Encoding.ASCII.GetString(byte[])
30 de mai. de 2009 · Linear range conversion is based upon the linear equation Y=Xm+n, where m and n are derived from the given ranges. Rather than refer to the ranges as min and max, it would be better to refer to them as 1 and 2. So the formula would be: Y = ( ( (X - x1) * (y2 - y1)) / (x2 - x1)) + y1.
