Greetings,
I recently discovered Mathematica's Format function, and it has been of great use to me. However, there is one thing that I want to use it to do, that I have yet to be able to. I could do this easily, though, if there is some Mathematica function that works as follows...
If I put a semicolon after inputting something in Mathematica, it evaluates what I input without outputting the result. The function that I am looking for is sort of the inverse of this.
I will call the function DoNotEvaluate[] for the rest of this post. Some simple input and output examples for the function that I am looking for would be...
Input: DoNotEvaluate[Sqrt[4]]
Output: Sqrt[4] - note that the output is not 2.
Input: DoNotEvaluate[Sqrt[2*2]]
Output: Sqrt[2*2] - note that the output is neither Sqrt[4] or 2.
Input: x=2*2; DoNotEvaluate[Sqrt[x]]
Output: Sqrt[4]
Does anyone know of a Mathematica function, or other Mathematica technique, that does what my made-up DoNotEvaluate[] function does?
Thanks for any help you can give.
