char c = 'E';
byte b = byte(c);
println(c + " : " + b);  // Prints "E : 69"

int i = 130;
b = byte(i);
println(i + " : " + b);  // Prints "130 : -126"
Description Converts any value of a primitive data type (boolean, byte, char, color, double, float, int, or long) to its byte representation. A byte can only be a whole number between -128 and 127, so when a value outside of this range is converted, it wraps around to the corresponding byte representation. (For example, byte(128) evaluates to -128.)

When an array of values is passed in, then a byte array of the same length is returned.
