Integer or Int

Description

• Whole number

• Used for counting

• Used for arrays indices (rows of data)

Examples:

Processing:

int count = 0;

JavaScript:

Do not use commas in your numbers!

Shortcuts (Assignment Operators)

Quick Math

+= means “add this”

-= means “subtract this”

*= means “multiply it by this”

/= means “divide it by this”

This updates the variable when used.

Example:

Processing, Java-based, and C-based:

int count = 2;

println(count);        // Prints "2"

count += 3;

println(count);        // Prints "5"

Python:

count = 2

print(count)        # Prints "2"

count += 3

print(count)        # Prints "5"

Adding or Subtracting 1

variableName++ means “add 1” or variableName += 1

variableName-- means “subtract 1” or variableName -= 1

This updates the variable when used.

Examples:

Processing, Java-based, and C-based:

float count = 0;

println(count);        // Prints "0"

count++;

println(count);        // Prints "1"

float health = 10;

println(health);        // Prints "10"

health--;

println(health);        // Prints "9"

This ++ shortcut after the variable name does not work in Python.
