Your examples of "FFD6" and "002A" both have 4 hex digits (i.e. 2 bytes). That's the same size as a Kotlin Short . So a simple solution in this case is to parse the hex to an Int and then convert that to a Short .

NettetDas Zweierkomplement (auch 2-Komplement – verallgemeinert b-Komplement (b Basis) –, Zweikomplement, B (inär)-Komplement, Basiskomplement, two’s complement) ist eine Darstellungsweise für negative Integer -Zahlen im Dualsystem, die keine zusätzlichen Zeichen wie + und − benötigt. Two's complement is a mathematical operation to reversibly convert a positive binary number into a negative binary number with equivalent (but negative) value, using the binary digit with the greatest place value to indicate whether the binary number is positive or negative (the sign). It is used in computer science as the most common method of representing signed (positive, negative, and zero) integers on computers, and more generally, fixed point binary values.

NettetFor the 2 's complement I am using the definition the OP posted in a comment "negative of a binary number represented by switching all ones to zeros and all zeros to ones and then adding one to the result". – dxiv Feb 26, 2024 at 22:07 The very first formula you use, I'm not sure why that's general. Nettet1. If you have a 13-bit 2's complement value, read it into a 16-bit signed variable, shift it left by 16-13 = 3 bits, then shift it right by three bits, done. int16_t value = readValue (); // readValue returns a 13-bit 2's complement number value = (value << 3) >> 3; // sign extend the value.
