WebThey allow encoding unsigned 64-bit integers using anywhere between one and ten bytes, with small values using fewer bytes. Each byte in the varint has a continuation bit that indicates if the byte that follows it is part of the varint. This is the most significant bit (MSB) of the byte (sometimes also called the sign bit ). WebJan Engelhardt wrote: Bit representation is left to the CPU, so 1 << 1 will always be 2, regardless of whether the byte, when sent out to the network, is 01000000 or 00000010.
