Pending issues with demo

#234

[Happypig375]

I think a demo label would be better?

[jiggzson]

Just plain demo?

[jiggzson]

@Happypig375 I'm moving all of your demo and documentation related issues here. I'm closing them but I'll reference them from this issue. Cool?

[Happypig375]

So when I need to open an issue about demo or docs, I need to post it as a comment here?

[jiggzson]

That would be awesome.

Divides 2 polynomials. ----------------------------------- Usage: nerdamer("divide(x)")

One argument missing. How can one process two things with only one parameter?

[Happypig375]

http://nerdamer.com/functions/Expression.text.html text() returns reserved names...?

[Happypig375]

The grammar police strikes:

http://nerdamer.com/functions/Expression.text.html

Pass in the string 'decimals' to ~always~ get the expression back as decimals. Pass in the string 'fractions' to ~always~ get the expression back as fractions.

http://nerdamer.com/functions/Expression.sub.html

Substitutes a given value with another given value. (Note the period) The value to substitute with.

http://nerdamer.com/functions/Expression.toTeX.html

Converts the expression to its LaTeX representation. (Note the period)

http://nerdamer.com/functions/Expression.evaluate.html

the expression is simplified but the functions aren't called

http://nerdamer.com/functions/Expression.variables.html

Gets a list of ~the~ variables contained within the expression. (Note the period)

http://nerdamer.com/functions/Expression.buildFunction.html

The order of ~the~ parameters is in alphabetical order by default but an array of arguments can be provided with the desired order. The array of arguments with the order in which they are preferred. change the order of variables by passing in an array with the desired order

http://nerdamer.com/functions/stdev.html

Returns the median symbolic function (Should be stdev?) if it cannot be calculated.

Enough for today.

A few issues while #284 was being written: After entering 2222222222222222.1, 'Load output to editor' outputs nothing. After entering 222222222222222.1, 'Load expression to editor' outputs nothing. After entering 22222222222222222222.1e0, it shows 222222222222222230000 (also the result when using 0.7.13), but 'Load output to editor' outputs 222222222222222222221. How come that button offer more precision than the library itself?

[Happypig375]

#306: Update the demo to 0.7.13 @jiggzson This is important for others to not mistakenly think that the library is missing something implemented in 0.7.13.

[jiggzson]

@Happypig375. Done.

[Happypig375]

Thanks, but putting solveEquations([x+y=3,3x+4y=3]) into demo results in TypeError: symbol.clone is not a function.

[Happypig375]

pfactor(78202389238903801/240831735646702201) => ​((23^2)⋅(21336787^​2))/​((2803^​2)⋅(99767^2)) (checks DECIMAL) => ​((529)⋅(455258479483369))/​((7856809)⋅(9953454289))

Should not expand the squares like the actual library.

[jiggzson]

Sounds a little counterintuitive, doesn't it? By definition a decimal number is a*10^n. Why would 23^2 not be expanded to 529 if you check decimal box? I'm surprised you haven't said anything about the brackets in pfactor. I mean those things redundant as heck. It's already on my TODO list.

[Happypig375]

By definition a decimal number is a*10^n. Why would 23^2 not be expanded to 529 if you check decimal box?

Why go half way then? Why don't literally return 0.32471795724474595? It is evaluating what it should not evaluate, it should only convert fractions in the form of a/b, not stuff like a^b. Also parity with text().

I'm surprised you haven't said anything about the brackets in pfactor.

Good catch! I overlooked this. :+1:

:laughing:

It's already on my TODO list.

Great!

[jiggzson]

Why go half way then?

I don't know if I agree. It's doing the conversion on the factors. If you want the factors stripped then just call evaluate.

I don't see how this is an issue since you're getting more not less. If you already have the desired output then just leave it as-is.

[Happypig375]

@jiggzson Let me rephrase. DECIMAL should only convert numeric fractions to numeric decimals. Switching this on causes the return value of pfactor to lose information about the powers on primes, which is a bug.

[Happypig375]

solveEquations([a+b=1,a-b=2]) demo=> [[a,3/2],[b,−1/2]] There is an extra layer of square brackets not actually present in the result.
