#toString

Returns a string representation of the value.

#Human Summary

Use it for compact exact string output. Use toFixed when fixed decimal places are required.

#AI Contract

#Signature

toString(base?: number): string;

#Parameters

#Returns

Returns a string.

#Behavior

• Without base, uses base 10 and follows EXPONENTIAL_AT for exponential notation.
• With base, converts using ALPHABET and rounds according to DECIMAL_PLACES and ROUNDING_MODE.
• Non-finite values return NaN, Infinity, or -Infinity.

#Examples

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

new Arith("255").toString(); // "255"
new Arith("255").toString(16); // "ff"

#Errors

• Throws if base is invalid.

#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.
