# Float

A float represents real numbers and is written with a decimal point dividing the integer and fractional parts. ^{[2]}

## Difference between an int and a float[edit]

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.^{[3]}

## Example[edit]

In PHP: You will remember PHP isn't a strictly typed language (although it can be set to be).

```
<?php
$a = 1234.65; // decimal number
$a = -1234.54; // a negative number
?>
```

In Python:

```
# decimal number:
a = 1234.65
# a negative number:
a = -1234.65
```

In Javascript:

```
// decimal number:
var a = 1234.65;
// a negative number:
var a = -1234.65;
```

## Standards[edit]

- Define the terms: variable, constant, operator, object.
