Hi,

Anyone know if there are any docs on variable types, e.g. float, int, word etc? I initially thought that C docs would be close enough, but it seems that's not the case.

I suppose this is a +1 for a manual! Or at least something on the wiki?

I was specifically looking for docs on 'word' as I'm not sure if a word should be getting truncated to 0 when assigned to a float.

For example:



correctly displays the sensor value, however



does not...

Hi Nick, normally when you would want to show float in a display line like that, you would have to replace the "d" with "f":



That should work for you. Although I believe the NXT does not support using floats for the sonar's value so it doesn't give you any decimal place values.

I have sent a message to our developer to see if he has any insight on this.

ROBOTC (and standard C) requires the user to properly match the format codes with the variable types in a print statement.

So if you use a "%d" code with a float variable you'll get unexpected results as the internal float variable representation will be interpreted as an integer in the print formating code.
