How to make decimal type field with number type in json schema?

[hyang691]

There are some fields with decimal as type in our typespec, when generating json schema, their type are string. I want to make sure its type is number.

I got suggestion below, but I get error "Argument '(anonymous model)' is not assignable to parameter of type 'valueof string'TypeSpec(invalid-argument)" when I add code @jsonschema({ type: "number" }) upper the field. Any suggestion?

Version used: "@typespec/json-schema": "0.55.0",

Suggestion:
To ensure that a decimal field type in TypeSpec is emitted as a number type in JSON Schema using the @typespec/json-schema package, you can use the @jsonschema decorator to explicitly specify the JSON Schema type. Here’s how you can achieve this:

Step-by-Step Guide
Define the TypeSpec Model: Create a TypeSpec model with a decimal field.
Use the @jsonschema Decorator: Apply the @jsonschema decorator to specify the JSON Schema type as number.
Example
Define the TypeSpec Model:
import "@typespec/json-schema";

model FinancialModel {
@jsonschema({
type: "number"
})
amount: decimal;
}
