Decimal places

[PierreScerri]

The 'Sum' function randomly throws a result with several decimal places. The node is being supplied with 2 values in an array from a 'Join' node. Each value has 1 decimal place.

Hi Pierre, Sorry for the delay! Not sure at the moment how to handle this: add a input field on the config screen perhaps, where you can specify the number of decimal places? Or did you have anything else in mind? Thanks for reporting this issue!

[PierreScerri]

My question was why is the sum of 7.9 & -3.3 = 4.60000000005? This messes up the display in Home Assistant and is also incorrect. Your idea of specifying the number of decimal places is interesting.

I have added a new checkbox to the config screen:

Would be nice if you could do some testing before I publish it on NPM. You can install it directly from this Github account like this (in your Node-RED folder):

npm install bartbutenaers/node-red-contrib-calc

Thank you for your efforts. I am running Node-red as an addon in Hassio. Added the package in the config and restarted the addon. The log says that:

[10:09:49] INFO: Starting installation of custom NPM/Node-RED packages...
+ node-red-contrib-calc@1.0.2

I think that it installed fine.

In Node-red, it still shows as 1.0.1. Don't know how to access the new version.

[bartbutenaers]

I assume you haven't installed it inside your Node-RED directory. Now you have somewhere the new version, but Node-RED still uses the old one... You should execute the install command inside the node-RED folder (e.g. cd $HOME/.node-red). Hopefully it works then, otherwise I just need to publish it to npm tonight ...

[PierreScerri]

Well the add-on should install it in its place I would imagine.

This is included in the Node-red addon config:

npm_packages:
  - bartbutenaers/node-red-contrib-calc

Had a look in the node-red folder in my config and the old version is there.

Don't know where else to look.

Hey Pierre, I have published this feature on NPM in version 1.0.2 Please reopen this issue if the rounding feature doesn't work as expected. Bart

[PierreScerri]

Thank you for efforts.

Unfortunately, as I've said before, I cannot install from the terminal as Hassio does not recognise the npm command. Tried installing from the add-on and it still reports 1.0.1.

So I can't test the new version.

[bartbutenaers]

Seems flows.nodered.org doesn't sync automatically anymore with npm. I have requested a manual refresh, and now it is updated to 1.0.3

[PierreScerri]

Got it. It works.

Thank you.
