Integers are your primary datatype for number storage. This yields a range of 32,768 to 32,767 minimum value of 215 and a maximum value of 215 1.
Arduino data types data types in c refers to an extensive system used for. Arduino eeprom how it works and how to use it with. Unlike standard longs unsigned longs wont store negative numbers, making their range from 0 to 4,294,967,295 232 1. Unsigned long is like int, but larger, ill explain. The type of a variable determines how much space it occupies in the storage and how the bit pattern stored is interpreted.
