Integers Floats.

Integers Floats.

Integers and floats are two different kinds of numerical data. An integer (more commonly called an int) is a number without a decimal point. A float is a floating-point number, which means it is a number that has a decimal place. Floats are used when more precision is needed.

int a = 0;      // Create a variable "a" of the datatype "int"
float b = 0.0;  // Create a variable "b" of the datatype "float"

void setup() {
  size(640, 360);

void draw() {
  a = a + 1;
  b = b + 0.2; 
  line(a, 0, a, height/2);
  line(b, height/2, b, height);
  if(a > width) {
    a = 0;
  if(b > width) {
    b = 0;
