+### Switch from integer to float
+
+To get a random float number, open the file `random-number/src/services.yaml` and replace the line
+```yaml
+class: MichaelKeiluweit\RandomNumber\RandomIntegerNumber
+```
+with
+```yaml
+class: MichaelKeiluweit\RandomNumber\RandomFloatNumber
 ```
+
+After that, execute the command `composer update`.
+Now the service will provide a random float number.
