Calculate much? Regular readers will remember a few items on the Mincey fault list. Poker. Ponies. Text editors. And calculators. I have all kinds; plastic and electronic with buttons, and various digital calculators, too.
Here’s one that you probably do not have on your Mac unless you are into algebraic expressions (or calculator collections). Chalk is dubbed just a calculator. It’s not. Chalk has been around a few years. It’s a bit quirky looking but you’re not likely to have a calculator that does what Chalk does.
Chalk is free but no necessarily easy to use unless you are 1) into complex calculators, or 2) a math wizard, or, 3) need to expand your brain. Chalk supports complexes, quaternions, matrices, lists, fractions, powers, expressions, primes, primality tests, and it even displays unambigous graphs.
Take a look:
This is not your Mac’s built-in calculator. Chalk can handle different bit representations, interpret an unsigned interger as a float, roll, shift, and since it supports uncertainty, you can display unambiguous graphs.
Chalk uses the built-in Core Data library in macOS High Sierra and that helps it to display sets of constraints (equalities and inequalities) so it can determine 2D areas. I’ve never had a Mac calculator that could output exact values in the numbers available in chalk.
Is this not the geekiest Mac calculator you’ve ever seen?
Chalk isn’t for the faint of heart or newbies to math, but it has a place in any Mac calculator collection. Caveats? Not much because Chalk is free, but it’s also an unsigned app from a Mac app developer without Apple certification. It seems to work well– once you get over the interface– but it’s hard to beat free.
