_If you are an App Developer and want to know more about how to include this into your App or how to let your App support BLL coding, goto the [[APP][Pro] Better Logic Library - For Developers](https://community.homey.app/t/app-pro-better-logic-library-for-developers/71761) Forum Topic._ This Topic describes the app for Users. ## Homey’s first real Library: Better Logic Library! Welcome to the Better Logic Library. An advanced logic library with variable and library management for Homey. This apps supplies your Homey with Better Logic and Libraries: - Variable management in a smart, integrated way. - Advanced action- and conditioncards with Better Logic, like Math.js. - Devices to directly manage the variables. - Datetime formatting, fully customisable, shared with other apps. - BLL coding and BLL expressions to use directly within other apps flowcards. - Custom functions to use within BLL coding and BLL expressions. - Libraries to use within BLL coding and BLL expressions, like Math.js and Lodash. - A File Server that can be consumed by other apps, like Simple (Sys) LOG, to serve files on you LAN or to download them on the Homey Mobile App or the Developertools. - Libraries for other Apps to consume, reducing app sizes and redundancies and improving management. - APIs for variable management, using the File Server or other BLL functions. Check out the (new) App Settings for all features and explanations, like BLL coding in supported apps! # BLL Coding Within all flowcards that supports BLL coding, you can add any BLL expression within the next codeblock: `{[expression]}`. You can use this f.i. within the Save Image Token flowcard from the [FTP Client App](https://homey.app/a/nl.qluster-it.FtpClient/) ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/c/b/cbdf7a46238eb6597776874ea66ce83adf3b2e2f.png) This image will be saved with the custom timestamp the user writes himself: ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/8/8/889b0386b12e500698969d8146bc9afec2dae9d0.png) Old Topic: **[[APP][Pro] Better Logic Library - Just some better logic, variable and library management](https://community.homey.app/t/app-pro-better-logic-library-just-some-better-logic-variable-and-library-management/5568)** ### Apps: > [@\[Profile\] Arie J.

# BLL Coding BLL codings are expressions within text-arguments in flowcards. In every App that supports BLL coding, for each text-argument in flowcards that goes through the BLL decoder, you can use `{[expression]}` . Within these expressions, you can use build-in modules, functions and your own customisable functions. ## Modules - \_ Lodash 4.17.21 - math Math.js 11.3.3 Example `The last one is: {[_.last(["1", "2"]) ]}.` Result: The last one is: 2. ## Build-in functions `date(format, date?, locale?, timeZone?)` This method will return the current date(time) in the entered format, with respect to the user defined locale (language) en timezone. Optionally you can supply the date(time), locale and/or timeZone. Example `Today is a {[date("dddd")]}` Result: Today is a donderdag # Date codings: ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/1/8/1823cdc0d4539b6ce854a796e1681d433a1d0afe.png) ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/b/f/bfe95cd79f3f77af981a23673f9fba40d293c615.png) ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/8/3/83214128c1cb757c725bcd99fb2bd4ea3f145a91.png) ---

# The `number` method Within BLL coding or expressions you can use the `number` method to convert numbers into text, based on your (or another) locale/language. It supports overloading, and can be used the following ways: - `number(number, decimals?, locale?)` - `number(number, style?, decimals?, locale?)` - `number(number, style?, styleOption1?, decimals?, locale?)` - `number(number, style?, styleOption1?, styleOption2?, locale?)` - `number(number, style?, styleOption1?, styleOption2?, decimals?, locale?)` ## There are 4 styles (decimal is the default): - decimal - currency - percent - unit ### Decimal Styleoption1: - standaard - scientific - engineering - compact\_short - compact\_long Styleoption2: - standaard - noGrouping ### Currency StyleOption1: - Any valid currency, like `USD` or `EUR` StyleOption2: - symbol - narrowSymbol - code - name ### Percent Has no styleoptions ### Unit StyleOption1: - acre - bit - byte - celsius - centimeter - day - degree - fahrenheit - fluid-ounce - foot - gallon - gigabit - gigabyte - gram - hectare - hour - inch - kilobit - kilobyte - kilogram - kilometer - liter - megabit - megabyte - meter - mile - mile-scandinavian - milliliter - millimeter - millisecond - minute - month - ounce - percent - petabyte - pound - second - stone - terabit - terabyte - week - yard - year StyleOption2: - long - short - narrow ---

I know, it’s cool right 🙂 But just added to test: KK kk hh h tt ISO No fixed GMT+ yet, that will only appear with KK or kk when you have a locale of EN f.i… (So for you, this will show GMT±, for me it shows CET). Fixed GMT+ will be Z, but no luck yet to complet this part without adding external node-modules. And i don’t want that, they are all a few MB, while my custom solution is less then 20kb. ---

Hi, Thank you for continuing development of this great app! I upgraded from the legacy Better Logic today and there seems to be an issue with Math.JS condition card. As POC I created T1 and T2 booleans and a test flow. [https://homey.app/f/luscxi/](https://homey.app/f/luscxi/) If Math.js expression is true. All variants of T1 and T2 being true of false is considered false. If Math.js expression is false. All variants of T1 and T2 being true of false is considered true. \ Andreas ---

Not sure if this is the same issue and all mathjs calculations are effected, but my BL math.js calculations does not seems to work anymore since november 14. The calculation is quite simple, it is for calculating the costs of a dishwasher cycle ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/d/7/d7ae3218dce581a674010776f7a9ba787b1b986d.png) ---

@aste and @Julian Solved in the current/latest Live version. I updated to the latest math.js a few weeks ago. Internally not different, but the evaluation call itself was changed. ---

There seems to be a bug in Math.js not validating Equal something == something is always false. I’ve tried with and without ““ to no avail. [https://homey.app/f/5nAeXj/](https://homey.app/f/5nAeXj/) and an even simplier version [https://homey.app/f/drmgXj/](https://homey.app/f/drmgXj/) Bitbucket bug: [QlusterIT / nl.qluster-it.BetterLogic / issues / #9 - Math.js not validating Equal — Bitbucket](https://bitbucket.org/QlusterIT/nl.qluster-it.betterlogic/issues/9/mathjs-not-validating-equal) ---
