feat: Introduce BooleanT and boolean functions (#17) This PR adds a boolean section, as well as an isNaN predicate on numbers. In a TypeDispatcher, when BooleanT is present, isNaN returns a BooleanT. However, in a numbers-only TypeDispatcher, it returns 1 or 0 instead. Moreover, when booleans are subsequently added to a numbers-only instance, isNaN properly reconfigures itself to return BooleanT. No predicates that depend on approximate equality testing or a configuration object are implemented in this PR. This PR also implements type matching and dispatching with implicit conversions, and adds an implicit conversion from BooleanT to NumberT.

feat: methods on Complex (#24) Adds all of the pocomath functions on Complex that do not depend on any unimplemented types or config properties, except quotient and roundquotient, where the design is murky. To get this working, adds some additional features: * Allows conversions to generic types, with the matched type determined from the return value of the built convertor * Adds predicate-based type patterns * Adds conversion from any non-complex type T to Complex(T) * Adds check for recursive loops in resolve (a key/signature depending on itself) Reviewed-on: https://code.studioinfinity.org/StudioInfinity/nanomath/pulls/24 Co-authored-by: Glen Whitney <glen@studioinfinity.org> Co-committed-by: Glen Whitney <glen@studioinfinity.org> 2025-04-25 14:17:34 +00:00			`import {match} from '#core/TypePatterns.js'`

refactor: change onType to match and take only one pattern and result (#22) Pursuant to #12. Besides changing the name of onType to match, and only allowing one pattern and result in `match()`, this PR also arranges that in place of an onType with lots of alternating PATTERN, VALUE, PATTERN, VALUE arguments, one now exports an _array_ of `match(PATTERN, VALUE)` items. Doesn't quite fully resolve #12, because there is still the question of whether `match(...)` can be left out for a behavior that literally matches anything (current behavior), or whether `match(Passthru, behavior)` should be required for such cases.
