[REBOL] Re: RF - Zine #6

From: anton:lexicon at: 8-May-2002 12:42

Yes it's good. I feel bad I haven't contributed anything. I noticed in Cyphre's draw tutorial this line of code: r: square-root ((power p/x 2) + (power p/y 2)) In tests I conducted recently I discovered that using power is only faster for powers >= 5. Better, then, to write simply: r: square-root ((p/x * p/x) + (p/y * p/y)) I remember this was discussed a long time ago, by more ancient rebols. This might also save a few cycles. Have to test it though: p2: p * p r: square-root (p2/x + p2/y) Anton.
