💖 NEAR(9) — the near component, bestie edition 💖

okay so this is a LinuxCNC HAL Component page, and honestly? it's giving "am I close enough tho" energy. the near component's whole job is deciding whether two values are roughly equal. that's it. that's the vibe. 🦋

✨ NAME ✨

near — figure out whether two values are roughly, like, basically equal. 💅

🌸 SYNOPSIS 🌸

loadrt near [count=N|names=name1[,name2...]]

so you load it into HAL like that, and you can either ask for count=N copies or name your own with names=name1[,name2...]. your call, bestie. ✨

🔥 FUNCTIONS 🔥

  • near.N — this one needs a floating-point thread, no cap, it will not run anywhere else. 💀

💜 PINS 💜

  • near.N.in1 — float, in. first value, come on in 🫶
  • near.N.in2 — float, in. second value, welcome to the function 💖
  • near.N.out — bit, out. the verdict ⭐

and here's what out actually means, like literally: out is true if in1 and in2 are within a factor of scale — that is, for in1 positive, in1/scale <= in2 <= in1*scale — OR if their absolute difference is no greater than difference, that is, |in1-in2| <= difference. otherwise? out is false. periodt. 🎀

side note because the first one is doing a lot of work: that factor comparison is written for in1 positive. the second one, the absolute-difference one, is just |in1-in2| <= difference and that's it. two ways to say "close enough", either one counts. 👑

🎀 PARAMETERS 🎀

  • near.N.scale — float, rw, default 1. the multiplier upgrade/downgrade factor for the "same-ish size" check ✨
  • near.N.difference — float, rw, default 0. the absolute wiggle room. yes, the default is literally zero, so set it if you want slack 💅
