Compute a number dimension

Where are raw numbers coming from?

There are two sources of raw numbers to be used in larger expressions:

1. Track any number dimensions provide a direct number encoded on cards themselves

   

2. Dimensions with numbers attached to values. First you need to enable the option on the dimension itself:

   

   Then you can associate numbers to values:

   

The expression language

On a Compute a Number dimension, a small expression language can be used to compute any number you'd like. For instance,

_.budget * _.progress.semantics

In those expressions:

• _ denotes the current card, on which the computed value applies
• _.xxx denotes the card value along the dimension whose name is xxx (camelCase)
• _.xxx.semantics denotes the semantics value, only for dimensions with numbers associated to values (second case of the earlier section)

Going futher

• Klaro Cards currently uses the Livescript language internally, if you need to go beyond simple arithmetics.
• In the future, we will migrate to Elo which is simpler, cleaner and more powerful. No worry, we'll migrate all formula for you.
