Ratio
On this page
One number to another, as written: 16:9.
Use it to record a proportion as people say it, such as a recipe's ratio. 16:9 and 32:18 stay two different values. For a share of a whole, use Percentage. For screens, use AspectRatio.

Example
Ratio { numerator: 16.0 denominator: 9.0 }text.parse(raw, as: Ratio) reads one from text that comes from outside. Text that isn't one at all fails malformed, such as 16/9, 16 : 9 or 16:.
Good to know
==tells you whether two are the same.<andlist.sort_bydon't take it, so sort by one of its parts instead.
In JSON
A string, in a request, a response or json.write:
"16:9""1.85:1""4.0:3.0"
Details
Text form, storage, how it is shown, and operations
Ratio is in the group Maths and data, 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: 16:9, 1.85:1 and 4.0:3.0.
How it is stored
It is stored in 2 columns, each named for the field, _ and its suffix. This is 1.85:1:
| Column | Type | Holds |
|---|---|---|
<field>_numerator |
numeric |
1.85 |
<field>_denominator |
numeric |
1 |
How it is shown to people
text.format(value, locale:) shows it to people in their locale.
With locale: Locale.en_gb:
| Value | Shown |
|---|---|
16:9 |
16:9 |
1.85:1 |
1.85:1 |
4.0:3.0 |
4.0:3.0 |
Operations
It also takes text.parse, text.from, text.format, json.read, json.write and ==. How every standard type behaves says how they work.
