| Examples | // Declare variable 'a' of type byte byte a; // Assign 23 to 'a' a = 23; // Declare variable 'b' and assign it the value -128 byte b = -128; // Declare variable 'c' and assign it the sum of 'a' and 'b'. // By default, when two bytes are added, they are converted // to an integer. To keep the answer as a byte, cast them // to a byte with the byte() conversion function byte c = byte(a + b); | ||||
| Description | Datatype for bytes, 8 bits of information storing numerical values from 127 to -128. Bytes are a convenient datatype for sending information to and from the serial port and for representing letters in a simpler format than the char datatype. The first time a variable is written, it must be declared with a statement expressing its datatype. Subsequent uses of this variable must not reference the datatype because Processing will think the variable is being declared again. | ||||
