Sage.
I want to define a function which presents everything in interval notation.
here is an input, for example: ``` In[1]: 34 In[2]: 53 ``` The output is very easy in this case: ``` [34,53] ```
But what if I have something like this? ``` In[1]: x > 4 ln[2]: x < infinity ``` Where I want ``` [4,infty) ```
Yup. @experimentX I know that you are rad at programming. Can you help?
what do you want to do?
rad? welcome to 1990s
@TuringTest You, please?
OK, on second thought, I want something like this: ``` Number 1: 4 Number 2: infinity Inequality type: closed. ``` And the output is... ``` [4,infty) ```
Just an interval notation.
I don't think you could do that, because the set of real number is both closed and open set.
[4, infinity) could be both (neither closed nor open) and (closed set)
try something like this around in mathematica `f[a_, b_] := If[NumericQ[a] && NumericQ[b], Print["Closed"], Print["Open"] ] ` ` f[1,2] ` BTW how did you put those colorful text?
I don't have Mathematica; my computer got formatted :-(
on what language are you planning to write it?
