Re: [Paparazzi-devel] one crash today, reach MAX_DIST_FROM_HOME, PID problem ?

[Gautier Hattenberger]

Hi,

I have added the exponentiation operator to the papgets, allowing to do 
sqrt (and more). You can find an example in conf/gcs/papgets.xml file:
      <papget type="expression" display="text" x="600" y="422">
        <property name="expr" value="NAVIGATION.dist2_home ** 0.5"/>
        <property name="size" value="15."/>
        <property name="format" value="HOME dist: %.1fm"/>
        <property name="color" value="white"/>
      </papget>

Update to master to use it.

Gautier
