Hi, new to SMath and trying to figure how to get the formula with the variable values before the final result.

I want to write

a: = 3
b: = 4
a + b


click = and get

a + b = 3 + 4 = 7


Is this possible?

Thks

Not how you wanted in single line but possible.

Thks a lot, it will do.

Just my decimal values get displayed as fractions

a := 3.5
b := 4.5
a + b = 7/2 + 9/2


I can live with that

You can write variables inside simple functions with this method.
This is not a practical way to write variables inside complex functions.
And it does not look good too. Yet it is better than nothing.
You can write a + b with Ctrl+Shift+K.

Hi Razonar,
it works perfectly well for initial formulas, but cannot find any way to use a previous result on a new one.

Cannot put all values in a single vals, the simbolic substitution will show in the second formula the formula (not the value) of the calculated value (ee).

Cannot either reuse names.

Any idea?

I have an idea, if someone has better you can use it.
Rewrite expressions and hide them inside areas.
Configure page setup with "no areas".
When you save as pdf or print, it will show as continuous.

But here is a humble suggestion.
SMath was not coded with intent to show intermediate results.
You are going to struggle very much with this approach.

I point out that in a previous post DeepButi used the function Clear("all" ) that despite not giving error does not have a feedback in SM: does not delete any variable.

Hi. This is another way. The feature request actually is here.

Using

Too easy to be true Final step uses fractions to substitute ... Use a:=1.2 in your example and you will see.

Actual formulas are for sure more complex so the data display is really confusing.

Hi. Thanks! ... but ... not ... but thanks. That behavior seems to be a bug or an oversight: set the decimal places in the output of an expression with None Optimization.

In the meantime, this could be a workaround, but could be dangerous, because change the stored value. Actually I don't really recommend it.

Ok, ok. Really it's a BIG THANKS.

:round(eval(... works perfectly well

:eval(round(... didn't.

Hello, John
I found no way to recover the symbolic Quaternion ?
Maple is not cracked for this demand ... Now, scratch your head.
Take care ... Jean.

Regarding the "Clear (arg)" function, my question is: is it possible to write an analytic function in Smath that has the same purpose ?!

PS - If so, maybe the moderator should separate a new topic. I have not studied this issue very well. Many apologies.

That's what Clear(,) does ... Maybe I don't understand analytical ?
