InterestRate

On this page

A yearly rate of interest, and the basis it is quoted on: 5.5% APR.

Use it for savings and loan rates. It keeps APR and AER from being confused. For a plain percentage, use Percentage.

Shape

Field	Type	Required?
`rate`	`Percentage`	Yes
`basis`	`InterestRateBasis`	Yes

example

InterestRate { rate: 5.5% basis: InterestRateBasis.apr }

The rate can be below 0%, as central banks' have been.
== tells you whether two are the same. < and list.sort_by don't take it, so sort by one of its parts instead.

An object of its parts, in a request, a response or json.write:

json

{"rate":"5.5%","basis":"apr"}{"rate":"4.75%","basis":"aer"}{"rate":"-0.5%","basis":"aer"}

Text form, storage, how it is shown, and operations

InterestRate is in the group Money and banking, and has been in Jadpo since 0.1.0.

It has no single text form, so text.from and text.parse don't take it.

It is stored in 2 columns, each named for the field, _ and its suffix. This is {"rate":"-0.5%","basis":"aer"}:

Column	Type	Holds
`<field>_rate`	`numeric`	`-0.005`
`<field>_basis`	`text`	`'aer'`

text.format(value, locale:) shows it to people in their locale.

With locale: Locale.en_gb:

It also takes text.format, json.read, json.write and ==. How every standard type behaves says how they work.
