Processing: Data Types

Processing supports below primitive data types.

a.   boolean

b.   char

c.    byte

d.   int

e.   long

f.     float

g.   double

How to define variable

    Syntax:

        dataType variableName = value;

    Example:

       int intVariable = 10;

        Here

            dataType is int

            variableName is intVariable

            value is 10

HelloWorld.pde

boolean status = true;

char charVar = 'a';

byte b = 100;
int i = 123;
long l = 12345;

float f = 123.45;
double d = 123.45678;

println("status = ", status);

println("charVar = ", charVar);

println("b = ", b);
println("i = ", i);
println("l = ", l);

println("f = ", f);
println("d = ", d);

When you ran the application, you can able to see below messages in console window.

status =  true
charVar =  a
b =  100
i =  123
l =  12345
f =  123.45
d =  123.45677947998047
