A concrete starting point
Serialize decimal strings into JSON without converting them through binary floating point. Round-trip trailing zeros and very large values, rejecting exponent notation and non-finite names under an explicit grammar.
Define the change
Describe the input, expected output and boundaries that must stay intact.
Inspect the work
Review the proposed edits and any commands before relying on their result.
Check the outcome
Compare actual behavior with the expected result. If a check fails, investigate it before applying more changes.
Lossless decimal serialization
A concrete starting point
function encodeDecimal(value: string): string {
if (!/^[+-]?\d+(?:\.\d+)?$/.test(value)) {
throw new Error("decimal.grammar");
}
return JSON.stringify({ decimal: value });
}The example is a starting point for a real project, not a claim that generated code is already tested. Adjust paths, dependencies and expected behavior to match your application.
