Applying rounding to base prices to quickly populate country prices

Rounding can be applied on the dashboard when populating country prices. If you know the base price of a product and want to quickly localize its price in local currencies and across different countries, you’ll need to decide how best local prices should be rounded. These “bulk” actions can be launched in the Prices section of the dashboard and generally follow the same rules as the rounding strategies described in the below section.

Applying rounding strategies to ephemeral prices

Ephemeral prices are often not well rounded, and need to have rounding applied to them. For example, a monthly product selling at 9.99 will be priced at 7.4925 after a 25% coupon application. To bring this price back to looking nice a rounding strategy can be applied to shift it to a nice number like 7.49 or 7.50.

The rounding strategies Corrily supports are governed by a simple language which is best described through example. Imagine you want to round up to .25, .49, .75 or .99 for prices between 0 and anything less than 100 and for anything equal to 100 or more you want to round to the nearest multiple of 50. A rounding rule to define this would then be:

  • 0_<100:f25_f49_f75_f99_nearest|>=100_inf:multiple_50_up

Notice how the rule is split into segments delimited by | each of which contains a range 0_<100 and >=100_inf followed by : and a range body which can either be:

  • a sequence of numbers to round to (f25_f49_f75_f99 where f denotes a float, i.e. the ability to round to say 4.59)
  • a function such as multiple_50 (the other important function is sigfig_<n_sigfigs> which rounds to the nearest number of significant figures.

Finally, each range body must end with either _down, _up or _nearest which defines whether numbers are rounded down, up or to the nearest number defined in the range body.
