WebJun 23, 2024 · A two-byte value is written as four hex digits. Thus $3F represents a byte value and $C008 represents a two-byte value. The first byte of a two-byte value is the most significant byte (MSB). The second byte is the least significant byte (LSB). So given the hex value $C008, the MSB is $C0 and the LSB is $08.

WebA Simple Proof. My simple proof shows that binary function, 3n + b, where n is the number and b is the least significant bit (LSB), is the same as the Collatz function. This is my proof. The LSB/rightmost bit of a number determines if it is even or odd (true) Every odd number 2x+1 becomes 3 (2x+1)+1 = 6x+4 by Collatz rules then (6x+4)/2 = 3x+2 ...
