ABS(9)

✨ ABS(9) — the HAL component that's literally just vibes (absolute vibes) ✨

okay so bestie, welcome to abs, a HAL Component 💖 she does one job and she does it flawlessly, no cap.

🌸 NAME 🌸

abs — compute the absolute value and sign of the input signal 🦋

like. that's it. that's the whole personality. and honestly? iconic.

---

🎀 SYNOPSIS 🎀

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

---

💅 FUNCTIONS 💅

• abs.N — requires a floating-point thread ⚠️ so like, don't try to run her on an integer thread, she will simply not show up. floating-point thread only, periodt.

not me warning you that N is the instance number — if you loaded with count=N you get abs.0, abs.1, … and every one of them needs that floating-point thread energy 🫶

---

✨ PINS ✨

okay bestie here's the whole squad, all the pins, per instance 🍓:

• abs.N.in float in — the analog input value. this is what you're feeding her, she's not picky, she takes it as it comes 💜
• abs.N.out float out — the analog output value, and it is always positive ⭐ like genuinely always, that's her whole thing
• abs.N.sign bit out — the sign of the input: false for positive, true for negative 👑 so like, bool-coded truth about which way the number was leaning
• abs.N.is-positive bit out — TRUE if the input is positive, FALSE if the input is 0 or negative 🙈 yes she's counting zero as not positive, don't come for her
• abs.N.is-negative bit out — TRUE if the input is negative, FALSE if the input is 0 or positive 💀 zero is neutral, zero is on no one's side, zero is the Switzerland of this component
