Hey Derek, thanks for the shout-out, but unfortunately you have the wrong Jack Moore. I don't want to steal the thunder from the real Jack Moore's blog. I couldn't find a Medium handle for Mr. Moore, but he's on Twitter at @jacklmoore if you'd care to give people another way to read stuff of his.
Great article though! I'd never thought about the shortfalls of out-of-the-box rounding in js, probably means I need to buff up.
