serializing Infinity creates invalid JSON #2482
Description
What version of Ajv are you using? Does the issue happen if you use the latest version?
8.17.1
Ajv options object
{}
Test case:
interface LoudnessMeasurement {
m: number | null,
s: number | null,
g: number | null,
g_seconds: number
}
const schema: JTDSchemaType<LoudnessMeasurement> = {
properties: {
m: { type: "float64", nullable: true },
s: { type: "float64", nullable: true },
g: { type: "float64", nullable: true },
g_seconds: { type: "float64" }
}
};
const ajv = new Ajv();
let serializer = ajv.compileSerializer(schema);
console.log(serializer({m:-Infinity, s:-12.0, g:null, g_seconds: 420.69}));Result:
{"m":-Infinity,"s":-12,"g":null,"g_seconds":420.69}
This JSON is invalid and should instead be:
{"m":"-Infinity","s":-12,"g":null,"g_seconds":420.69}
