FrameRate

Frames a second as an exact fraction, written 30000/1001 for 29.97 and 25/1 for 25: both parts at least 1, held as written.

Media and visual; not ordered; since Jadpo 0.1.0.

Make one

Build one from its fields, FrameRate { numerator: ... denominator: ... }.

text.parse(raw, as: FrameRate) reads one from its text; text that isn't one at all fails malformed, such as 29.97, 30 or 0/1.

Fields

Text, JSON and storage

text.from writes its canonical text, the one form text.parse reads back. JSON sends its canonical text as a string.

It is stored in 2 columns, each named for the field, _ and its suffix. This is 24000/1001:

Shown to people

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

With locale: Locale.en_gb:

Operations

It has the contract's own operations: text.parse, text.from, text.format, json.read, json.write and ==. It isn't ordered, so < and sorting don't take it. Every standard type meets one contract says how they work.
