#isLessThanOrEqualTo

Test whether the receiver is less than or equal to another value.

#Summary

Use this predicate instead of JavaScript comparison operators to preserve decimal semantics.

#AI Contract

#Signature

isLessThanOrEqualTo(n: ArithValue): boolean;
isLessThanOrEqualTo(n: string, base: number): boolean;

#Parameters

#Returns

Returns true when the receiver is less than or equal; otherwise returns false.

#Behavior

• Converts the argument with new Arith(n, base).
• Returns false when comparison is not satisfied or comparison is indeterminate because of NaN.
• Does not mutate either value.

#Examples

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

new Arith("2").isLessThanOrEqualTo("2"); // true

#Errors

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

#Agent Notes

• Use comparison methods instead of JavaScript comparison 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.
