# 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);
stroke(255);
}

void draw() {
background(0);

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;
}
}```

## Functions Used

stroke()

Sets the color used to draw lines and borders around shapes

size()

Defines the dimension of the display window width and height in units of pixels

if

Allows the program to make a decision about which code to execute

setup()

The setup() function is run once, when the program starts

draw()

Called directly after setup(), the draw() function continuously executes the lines of code contained inside its block until the program is stopped or noLoop() is called
