I tried casting the winddir as a int in the file generation and the file
shows an int for wind and winddir but the _get_as_float() must have changed
them to float
Enter code here...pi@pi3four:/home/weewx $ cat /var/ramdisk/wxdata
outtemp=0.0
intemp=63.1249993131
outhumidity=56.8
inhumidity=30.367590633
wind=2
winddir=117
radiation=0.0
barometer=30.1184384389
rain=0.0
pi@pi3four:/home/weewx $
