Great to hear! I think this is going to be a really useful plugin. Saves me from having to pop up a calculator

Again, Excellent work!

V0.2.0

Adds support for in-block configuration (based on @tessus's idea) which can be used to set display options as well as notation.
Adds support for inline calculations

The plugin is not yet available on the Joplin plugin repository, but I have published, so it should be available soon!

Enjoy!

This plugin reminds me of https://soulver.com/, very useful, thank you!

This is cool. Are there any plans to integrate these so they can be used with mobile apps?

Perhaps plug-ins can be synced too?

CalebJohn · 2021-01-24T19:35:11.758Z

I don't know if there are any plans to introduce the plugin system on mobile. I do know however that even if that does happen, it will be unlikely that this plugin gets ported to mobile, it relies heavily on integration with the desktop markdown editor and wouldn't work at all on mobile.

Very useful thanks! Am using it in one of my notes now.

V0.3.1

Adds the built in total variable which accumulates on groups of lines

image842×592 40 KB

In this example you can see that the total variable takes on the value of the sum of all the preceding lines.
A new syntax is also added which will allow users to explicitly signal that a line is meant to add to (or remove from the total variable

+= 2+2 // Will add 4 to the total variable
-= 2+4 // remove 6 from the total variable
total => -2

The total variable is reset to zero if there is a line break between math lines, or if a new block is started.

I've also started adding examples to the github page. If anyone using this plugin has a good example, please send it my way and I'll add it! (With credit of course)

The update is available now on the Joplin plugin repository!

V0.4.0

Now supports currency conversion (rates updated daily)

Default settings can now be changed in the Tools -> Options -> Math Mode menu (Preferences on MacOS)

The update has been pushed, so should be available from within Joplin by tomorrow!

CalebJohn · 2021-05-22T02:52:08.417Z

V0.5.0

Clicking on a math result will copy it to clipboard
Add fixed formatting
Add range options for the auto formatting
Add option to disable currency fetching

The update is pushed and should be available soon.

CalebJohn · 2021-08-21T15:42:59.942Z

V0.5.2

Just a small patch to catch up with some of the theme updates that have happened in the base app recently

Math blacks will now be monospace (like all code blocks in Joplin). I haven't added an option for this yet, but I will consider it if there is demand.
Fixed a bug causing the plugin to interfere with code backgrounds
- Should fix @tessus's problem

As always, the update has been pushed and should be available shortly.

CalebJohn:

Should fix @tessus's problem

Yep, it did. Thanks.

@CalebJohn
First of all, thanks for this useful plugin
Secondly, I doubt the way to get a result with only one decimal e.g., =7/12=0.583333
I have checked in math.js | an extensive math library for JavaScript and Node.js founding we should add ROUND or ROUNDUP expression but, trying in different way and it is not working.
Could you help me suggesting the exact expression to add in Joplin for getting the result with only one decimal using the Math Mode plugin?
Thanks

CalebJohn · 2021-11-25T02:41:13.849Z

Hi @Eduardo
You have a few options that I'll list here (in order of usefulness)

1

= round(7/12, 1)

2

```math
precision: 1
7/12
```

3

Open the plugin settings (Tools->Options->Math Mode on Linux/Windows, and Joplin-> Preferences -> Math Mode on macOS).
Change "Precision" to 1.
I think this is least desirable because it will change the precision for all notes.

Eduardo · 2021-11-25T12:28:10.529Z

Hi @CalebJohn
Thanks for the advise. I know there is an option to set up in a plugin but as you mentioned this set up impacting in all the notes in a same way. Thank for the help.

CalebJohn · 2023-09-27T06:22:10.877Z

v0.6.1

Changed the precision option to more clearly state that it refers to number of digits of the results.
Removed the "Upper Exponent" advanced configuration option. There is too much overlap between this option and precision and having both creates the opportunity to mess up the configuration (the default values of these two have been incompatible for the last 2 years, causing subtle issues with some results)

Eduardo · 2023-09-27T14:37:34.070Z

@tessus
Should it be updated to 0.6.1?

tessus · 2023-09-27T14:52:25.562Z

The version number in the manifest is wrong. Please ping @CalebJohn to update it accordingly and release 0.6.2.

CalebJohn · 2023-09-27T19:01:36.325Z

Sorry about that, I thought I had set the manifest to automatically update, but it clearly didn't. v0.6.2 should be good to go

Great plugin! I have some questions. Is this thread where you primarily discuss Math Mode, or is there somewhere else you prefer?

Thinking I'd like to add some measurement units. Don't know if I should try adding them to math.js or just locally. Would like to use them with your plugin.

CalebJohn · 2024-04-27T05:21:55.853Z

I prefer to do discussion here, but once it's a concrete feature request, I'll track it on github.

If it's a fairly standard unit I think adding it to mathjs would be best (then I'll update the plugin to use the newer version of mathjs). Probably this plugin should have some global configuration that allows for adding units and functions etc. but it will be best to start with mathjs if possible.
