Examples

    byte a;         // Declare variable "a" of type byte
    a = 23;         // Assign "a" the value 23
    byte b = -128;  // Declare variable "b" and assign it the value -128
    byte c = a + b; // Declare variable "c" and assign it the sum of "a" and "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.

Syntax

    byte var
    byte var = value

Parameters

var | variable name referencing the value
value | a number between 127 to -128

Usage | Web & Application
Related | int float boolean
