Plan: Fence Radius truncated to integer

[rmackay9]

The Plan screen's Fence list has a "Radius" parameter which accepts floating point numbers but seems to truncate them to integers. The issue can be reproduced by doing this:

• Open MP and start the Simulator (Rover or Copter)
• Open the Plan screen and select FENCE from the drop-down on the top right
• Click on the map in a few places to create FENCE_CIRCLE_EXCLUSION fences (BTW, I think these string could be made more readable by changing to "Circle Exclusion" but I think I've already raised another issue about this)
• Change a radius to "3.5" and press "Write"
• Push the "Read" button to read back the fences and note that "3.5" has been changed "3".

I suspect that MP is changing this field to an integer because it is normally used for the "p1" parameter of commands which is always and integer. From what I can see the MAV_CMD_NAV_FENCE_CIRCLE_EXCLUSION message accepts floating points but please tell me if I'm wrong.

i believe this is AP dropping the decimals

Found the bug. It's in ArduPilot. Closing this.
