# Preface

### Primitive Data Types

#### Null

This value type can override any other type and essentially means "nothing" not even 0, its the lack of a value whatsoever

If you open a box thats supposed to have a number in it, and you found null, the box would just be empty

#### Boolean

A boolean value is true or false, it cannot be anything else

See [Sqlite](sqlite.md#Boolean) for more information on boolean values within sqlite.

#### Integer

An integer is any valid number without a decimal, such as 1, 5, 68, 421, and even negative numbers like -42, -99999, or -0 in some cases

#### Real Number (floating point number)

A real number is any real number, such as 1, 73, 45, 0.6, 255, -9.8, 200000000, and so on, it may use a decimal value unlike integers.

We should prefer Integers over Real Numbers unless a decimal place is absolutely required:

There are resolution limitations to consider, the number of bits a computer can store in a single value is finite, a 32 bit number only has 32 bits, meaning there can only be about 2 billion and some possible combinations.

Real numbers do not change this, there are only 2 billion or so different values to a real number, so the smaller you go, the more likely you are to accidentally "snap" to a nearby number that can actually be stored,

The same thing happens when you go high enough.

Here are some good videos on the topic.
