Type Description

char	Single byte data type, can store a single character or number 0 to 255
short	16-bit integer, can store numbers from �32,768 to 32,767
int	32-bit integer, can store from �2,147,483,648 to 2,147,483,647
String	Stores a string of characters
float	A 32-bit floating point number. Accuracy normally about 6 decimal places, but varies depending on the size of the number being stored.
bool	a variable that stores either 'true' or 'false'

You will normally only need to use the int and String data types. The smaller types are only useful for conserving memory if you are creating a very large number of variables.

To declare a variable, write the type followed by the variable name, then a semicolon. For example:

int my_variable;

declares a new 32-bit integer called my_variable

WARNING: When using the float data type, you may find that the == and != operators don't seem to work properly. For example:

float result = 2.0 * 3.0;
if (result == 6.0) {
  Display("Result is 6!");
}

float result = 2.0 * 3.0;
if ((result > 5.99) && (result < 6.01)) {
  Display("Result is 6!");
}
