In practice, few modern systems use padding bits, or even representations other than 2's-complement, but the standard still permits such oddities.

When is it necessary to use "float" instead of "int"?

Web1 day ago · Integers are your primary data-type for number storage. On the Arduino Uno (and other ATmega based boards) an int stores a 16-bit (2-byte) value. This yields a range of -32,768 to 32,767 (minimum value of -2^15 and a maximum value of (2^15) - 1).

WebJul 1, 2024 · And, uint8_t is ALWAYS an 8-bit value, regardless of what platform you are running on, while int, long, etc. can be different sizes on different processors. On AVR, int is 16-bits, on ARM and ESP int is 32-bits. One AVR, long is 32-bits, while on some other platforms it is 64-bits. 1 Like gfvalvo March 3, 2024, 5:06pm 15 RayLivingston: WebMay 2, 2011 · Long is the Object form of long, and Integer is the object form of int. The long uses 64 bits. The int uses 32 bits, and so can only hold numbers up to ±2 billion (-2 31 to +2 31 -1). You should use long and int, except where you need to make use of methods inherited from Object, such as hashcode.

WebAug 9, 2024 · On the Arduino, an "unsigned int" is a 16-bit quantity so a "word" is also a 16-bit quantity. On the ESP8266 and ESP32, an "unsigned int" is a 32-bit quantity. The header file for the ESP8266 corrects for the change in the size of integers by equating "word" with "uint16_t" but no such adjustment has been made for the ESP32.
