I have a value I'm taking from a sensor module, which is 2500 when the sensor is facing a light source. This reads to my code and can be saved perfectly fine. When I try to find the weighted average of a set of values (2500*1000+2500*2000+2500*3000 etc), the Arduino comes out with very weird answers. For example
If I just compute 2500*1000 on its own, the answer still comes out the same! The results come out negative if I use int so I switched to using double (just in case the values created were too big), this stops producing negatives as expected but the result is still like it is above.. I have no idea why.. any ideas?
