BQN utilities. Scripts resembling these may become part of a standard library at some point but for now they're not. They shouldn't be assumed to be stable or well-tested.

For usage, see export lists at the top of each file. Run all tests with bqn test/main.bqn, or any individual test using the same name as the file in the main folder. Similarly, files in the benchmark/ folder run and report on performance measurements for the script of the same name.

Text and file formats:

• strings.bqn: common string operations like split, replace, and so on (no regex)
• json.bqn: JavaScript Object Notation
• csv.bqn: Comma-Separated Value file format
• xml.bqn: eXtensible Markup Language

Math:

• primes.bqn: fast sieve with typical prime and factoring utilities
• matrix.bqn: matrix decompositions and tools; APL ⌹ is Inverse⊘Solve
• polynomial.bqn: complex polynomial tools and solvers
• min.bqn: optimization/minimization methods
• roots.bqn: find zeros of real-valued functions
• big{nat,int}.bqn: utilities for arbitrary-precision numbers

Other:

• datetime.bqn: time and date, handling formats other than BQN's native •UnixTime
• hashmap.bqn: prototype for •HashMap, now obselete in CBQN
