InterestRateBasis

On this page

What an interest rate is quoted as: aer, apr or flat.

Use it as part of an InterestRate, which most apps want instead. aer is for savings, apr for borrowing, and flat is a rate on the sum first lent.

Shape

One of these 3 values:

InterestRateBasis.aer, InterestRateBasis.apr, InterestRateBasis.flat.

Example

example
InterestRateBasis.apr

text.parse(raw, as: InterestRateBasis) reads one from text that comes from outside. Text that isn't one at all fails malformed, such as apy, annual or a p r.

Good to know

  • == tells you whether two are the same. < and list.sort_by don't take it.

In JSON

A string, in a request, a response or json.write:

json
"aer""apr""flat"

Details

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

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

Text form

text.from writes one standard text form, the same form text.parse reads back: aer, apr and flat.

How it is stored

It is stored in one column named for the field, of type text. apr is stored as 'apr'.

How it is shown to people

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

With locale: Locale.en_gb:

Value Shown
aer AER
apr APR
flat flat

Operations

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