# Fraction node

The Fraction node returns the fractional part of an input, also known as the decimal part. The range is 0 to 1. For example, the fractional part of 3.75 is 0.75.

The Fraction node calculates the result using the following formula:

```
fractional_part = input - floor(input)
```

As a result, the node returns a positive value if you input a negative number. For example, the fractional part of -3.75 is 0.25.
