#toJSON

Returns the same string form as valueOf() and is used by JSON.stringify.

#Summary

Use it implicitly through JSON.stringify when serializing Arith values.

#AI Contract

#Signature

toJSON(): string;

#Parameters

#Returns

Returns a string.

#Behavior

• Includes the sign for negative zero.
• Does not accept a base argument.
• JSON.stringify calls this method automatically.

#Examples

import { Arith } from "@teakit/arith";

JSON.stringify({ total: new Arith("0.3") }); // "{\"total\":\"0.3\"}"

#Errors

• Does not take user arguments; no argument validation is performed.

#Agent Notes

• Import from @teakit/arith; prefer import { Arith } from "@teakit/arith".
• Use new Arith(...) to construct values. Do not generate Arith(...) as a function call.
• Use string inputs for exact decimal values, especially money-like values.
• Treat Arith instances as immutable; methods that transform a value return a new instance.
• Do not mutate internal fields such as c, e, s, or _isArith.
