💖 dot — DOT(3G) 💖

okay bestie, gather round, because today we're talking about dot from the 3G manual — the little function that does the most and asks for so little. ✨

🌸 NAME 🌸

dot — calculate the dot product of two vectors. that's it. that's the whole job. and she does it flawlessly. 💅

✨ DECLARATION ✨

here's how you call her, no cap:

float dot(genType x, genType y);

double dot(genDType x, genDType y);

🎀 PARAMETERS 🎀

  • x — the first of two vectors. your main character vector. 👑
  • y — the second of two vectors. the supporting lead. 🫶

🦋 DESCRIPTION 🦋

dot returns the dot product of two vectors, x and y. like, literally this:

x [ 0 ] ⋅ y [ 0 ] + x [ 1 ] ⋅ y [ 1 ] + ...

that's the vibe. multiply the matching components, add it all up, done. it's giving mathematics. 🌈

⭐ VERSION SUPPORT ⭐
