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.
In a formula it means absolute position. It means taking a number or formula from a particular cell, regardless of where you move the formula. For example, if your formula says =B11+B12, then you copy and paste that formula one cell down, it will be b12+b13. But if you use $B12 + $B13, and then copy the formula one cell down, it will still be B12+B13.
