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.
When you concatenate text, you surround the text with double quotation marks so Microsoft Excel recognizes it as text. Otherwise, you'll receive an error. Excel then uses the text within quotes but discards the quotation marks. This poses a problem when you actually need to concatenate the double quotation marks themselves. However, Excel has a special character function that allows you to enter such marks. 1. Open your spreadsheet in Microsoft Excel.
