A real message using tag 228

Where tag 228 appears

Requiredness is a property of the message, not of the field: the same tag can be optional in one message and conditionally required in another.

Wire format

A decimal number. The wire form keeps its trailing zeros, which is why decoders expose the raw string alongside the parsed number. @boarteam/fix parses the value as a number and reports parse/invalid-float when it does not lex as one; the raw string is kept so precision and trailing zeros are never lost.
