WebMay 27, 2024 · on the arduino documentation it describes that arduinos with the SAMD chip store the integers in 4 bytes. 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). 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. ...

WebJul 22, 2024 · A better classification would be: C and C++: char, int, long, unsigned long. "Arduino": byte, word. inttypes: int8_t, int16_t, int32_t; uint8_t, uint16_t, uint32_t. I generally avoid the Arduino-specific types, as they are quite non-standard, and do not usually exist outside the Arduino world. As for the other types, just like Michel Keijzers ...

WebJan 27, 2024 · RE: grundelegende Frage: int vs const int Zum einen ist es sicherer, weil der Compiler keine Änderung zulässt an diesen Konstanten. In vielen Fällen ist es auch schneller und RAM-sparender, weil der Compier - wo immer möglich - gar keine 'Variable' im RAM anlegt, sondern in den Anweisungen direkt den konstanten Wert verwendet. WebMay 6, 2024 · The problem is that, as stated, you can't expect accuracy in the eigth digit of a number that is stored in four bytes. Arduino has a float, but double, which in most processors/languages would be eight bytes long, is just the same as float in Arduino. You are up against a limit that can't be changed. jrdoner angeloziel April 19, 2024, 3:13am #3
