Integer Storage

[FredA]

If I store a negative number in a variable that is int8_t, or int16_t or int32_t and then print it in binary, it is always 32 bits long. Does a T3.6 store all of these as 32 bits?

And what is the endianness?

No, but the C default conversion rules state that char, short, and variants always get converted to int or unsigned int. C++ inherits these rules. Given that the Print.h include file defines rules for uint_t, int, etc. and not int_t, int16_t, short, or signed char, you are seeing the default conversion to int.

And what is the endianness?

Teensy 3.6 (and all Teensy) uses little endian storage, least significant byte first.

George, are you a robot?

Seems like since reading prior posts shows good answers

<edit>: Seems George was a ROBOT … another vapid post with a link this time … bye bye George.
