#modulo

Return the remainder after division.

#Summary

Calculates the remainder using the current modulo mode.

#AI Contract

#Signature

modulo(n: ArithValue): ArithInstance;
modulo(n: string, base: number): ArithInstance;

#Parameters

#Returns

Returns a new Arith instance. The receiver is not modified.

#Behavior

• The receiver and argument are converted to Arith values.
• The receiver is not mutated; a new instance is returned.
• The quotient used to calculate the remainder is selected by MODULO_MODE.
• The default mode matches JavaScript remainder sign behavior.

#Examples

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

new Arith("7").modulo("4").toString(); // "3"

#Errors

• Throws if base is invalid.
• Throws if the input value is invalid while STRICT is true.

#Agent Notes

• Do not use JavaScript arithmetic operators on Arith values.
• 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.
