[R] Funky calculations

[Mark Fowler]

This a joke? The values differ between the TRUE and FALSE syntaxes. The FALSE computes to 1.0, which is not greater than 0.

Subject: [R] Funky calculations

Hello,

I found something strange and maybe I am going nuts but this does not make
sense:

>  (0.4 + 0.2 + 0 + 0.3 + 0 + 0.1) > 1
[1] TRUE

I tried it on my mac M1 (R v4.1.2) and my Linux box (R v4.0.4). If I use
other values, it does not work (see below). It seems only that combination,
granted I did not try them all.

>  (0.4 + 0.2 + 0 + 0.2 + 0 + 0.2) > 1
[1] FALSE

Am I missing something?

Cheers
