in reply to Re^8: Split any number into string of 8-bit hex values (=1 byte)
in thread Split any number into string of 8-bit hex values (=1 byte)

How does an 8-bit register in an I2C device "know" that an 0xc8 byte started out as 20010 or as -5610? One can make similar arguments about 16- and 32-bit registers.

I share the misgivings expressed by LanX here.
