(Perhaps this isn't the right place to ask questions about I.C. but it is
related to the handy board so I will continue)
I am trying to write a program that uses the lego sensors and multiplies
them by constants that are floats. The expansion board returns integers for
the lego sensors so I have a problem there as multiplying floats and ints
isn't permitted by I.C. as far as I can make out. (the program returns an
error saying that <float> * <int> isnt permitted)
Also when I calculate these values I want to use them to determine how long
to leave motors on. I am turning the motors on full, leaving them on using
the mseconds() function and then turning the motors off - again using the
mseconds() function in order to create an exact force on my model. This
function requires long ints so I must convert my answers from above which
are floats into long ints. Again my problem is that as far as I can see
there is no way of converting between these different variables.
Any ideas from anyone?
Thanks,Brendan

| You have to coerce the int to a float, e.g: int i= 7; float j= 3.; float result; result = j * (float)i; The above should work. Please let me know if not. Fred (...) (22 years ago, 25-Feb-02, to lugnet.robotics.handyboard)
