# Definition

A float (short for floating-point number) is a data type that has 32 bits of space.

# Relevance

Floats are commonly used for complex numbers in programming. Being floating-point numbers, floats can hold decimal precision.

# Explanation

Floats can be used for arithmetic expressions such as addition, multiplication, division in programming.

```
float a = 5f; // notice the f after the number, this is necessary to specify that the value is a float.
float b = 2.5f;
float result1, result2, result3; // You can also declare several variables of the same type this way.
result1 = a + b; // result1 = 7.5
result2 = a * b; // result2 = 12.5
result3 = a / b; // result3 = 2;
```
