SMath Studio - mobile version now available 3

[jhardy1]

This might be old news to some, but I just discovered that SMath Studio is now available as a free mobile app for Android and iOS:

LPS for you... downloaded it and seems to work pretty well.

There's no ctrl-w for units like the pc version, but can still use single quote (example 'in) or insert / units.

There seems a small bug that if I type X:=5, it puts in X:=5=5. That's not insurmountable...you can edit out the extra stuff at the end.

Do you know if files can be shared between mobile and PC versions?

hmmm, If I type X=5, the result is X:=5
That's easier than going back and editing out the extra stuff.
I guess it is an intended shortcut so we don't have to go find the colon ) key so often.

Yup. I moved a *.sm file from my PC to my phone. Could open it, view it and edit it.

Have had it on my phone for some time. Can't replicate this "bug" using either "=" or ":" Note that typing ":" automatically inserts ":=", so it's possible that if you are actually typing both characters SMath thinks you're typing ":" followed by an "=" which results in two separate actions.

TTFN (ta ta for now)
I can do absolutely anything. I'm an expert!

It is definitely reproducable for me on the mobile app for android that typing X:=5 gives X:=5=5

But I no longer consider it a bug. You are right, it is just a result of shortcut behavior that I was not previously familiar with (I used to type the full := on pc and it never caused a problem there). I can type either : or = and the result is := in this example.

I do have another question though. Are the menu options available anywhere?

For example on pc to change the number of decimal places, I selected tools / options / decimal places.
I don't see any menus on mobile. Can I adjust the same decimal places setting in mobile?

I've just been playing with SMath Studio (Android) for an hour or so - it seems to me that the input syntax / parsing is exactly the same as the browser version "SMath Studio in the Cloud"

https://en.smath.info/cloud/

and I assume they use a lot of the same code.

Typing a colon automatically generates a displayed := waiting for you to enter your expression. Typing a colon followed by an equals sign places a second trailing equals sign which is where the "in-line evaluation" of your expression appears.

For example typing the following sequence of characters (to assign a length of 5 inches to variable x) without typing an equals symbol
x:5'in
displays
x := 5 in

Typing the following sequence of characters (to assign a length of 5 inches to variable x, and evaluate it in default units - in my case metric units), by typing an equals symbol (BEFORE or after entering the expression)
x:=5'in
displays
x := 5 in = 0.127 m

I haven't been able to find any on-line documentation, and a lot of menu options seem to be missing (e.g. modifying display formats etc), so you might need to send your file to the desktop version or browser version to access those features. It's also possible that a "full-featured" SMath worksheet created in the desktop version might not work properly in the mobile version, but I haven't tested this. Even so, even with its limited feature set, it'll be a very useful tool for me - I'll load up a few of my common calculation worksheets onto my phone for doing quick checks in the field. (I certainly can't complain about the value for money!)

I did notice that at the bottom right of the screen, there is a double-button. The left button (default) opens a basic menu of options, and the right button opens a translucent custom keyboard, with quick access to common mathematical operators, units, etc. It takes up quite a bit of screen "real estate" on my phone (although you can see the underlying worksheet through it), but it works very well on my 10" tablet.

I didn't even know there was a web browser version of smath! (I've been using a *.exe file on my pc). That looks pretty handy.

Two other things about that smath custom keyboard you mentioned
1 - it is way less intrusive if you turn your phone to landscape mode (then you can actually see what you're typing).
2 - I noticed when you bring up the letter keyboard, you can toggle the letters to greek symbols easily.
