Hello, i’m trying to rebuild a float number sent on a serial line. I had trouble working on a bitwise operation. Code : [image] I expected a byte to be 8bits of length but I can only fill the array with 4bits values (Ex : 0xF) See the byte processing reference : Datatype for bytes, 8 bits of…

[image] moimat56: I expected a byte to be 8bits of length but I can only fill the array with 4bits values (Ex : 0xF) Actually you can use up to 0x7F, which is the hex value for 127. And you can use -0x80, hex for -128. So the entire signed range of the byte is definable in hex, it just doesn…
