Shouln't Pi and Phi be stored under constants? After all they are constants
and showing them under variables is confusing O_o

``` Hi Enrico. I think you're right in the sense that they should be available is some constant category. But it's also handy if you can just type "pi" in you expression, and (immutable) variables are the only way to achieve it. But again, they should also be constants, yes. ```

``` I think that "immutable variables" are a contradiction. There should be something like "unnamed constants", "named constants" and "variables" (all variables have a name, of course). ```

``` An immutable variable is just an implementation convenience. Ideally, it would work

like you've described. The user should be able to assign a string to represent a constant. I'll keep this in mind for this feature. Thank you! ```

``` How can pi be a variable? ```

``` What about e, base of the ln()? ```

``` "e" and all most common calculus/number theory constants will be available. Would be nice to have a list though. ```

``` 'e' should indeed be available, regardless of how it is classified. The exp(1) is a temporary workaround, and you can set e yourself by performing e=exp(1) in speedcrunch. ```
