Overview. For sensors like the VEX Ultrasonic sensor that return a range of values, we often simply want to check if the returned value is more than, equal to, or less than some value called a threshold. For example say that we have the sensor set up and are driving around, but we need to stay at least 5 inches (127 mm) away from any obstacles.
How do I tell excel to treat a  in an excel formula as a ? :) Excel reads quotation marks as signifying text inside, but my text field requires a  to be included in it as well, so I need to somehow tell Excel that the  is part of the text field within the two s :p. Does that make sense? Mike.
It means that the row or column which comes after the dollar sign is anchored or absolute. When you copy Excel formulas, they will copy cells referred in that formula relative to the position where they are being copied to. Let's take a simple example. In Cell A1, I have the value 10. In Cell B1, I have the formula +A1.
