+The `float.random` processor will set the payload to a random float between the specified `min` and `max` value.
+
+- **type**: `float.random`
+- **params**:
+    - **bitSize**: (optional) the bit size of the float to generate, defaults to 32
+    - **min**: the minimum value for the random float (inclusive).
+    - **max**: the maximum value for the random float (exclusive).
+
+### Example
+This would generate a random 64-bit float between 1.1 and 1.5 and set the payload to that value.
+```
+- type: float.random
+  params:
+    bitSize: 64
+    min: 1.0
+    max: 1.5
+```
