ABS_S32(9)

✨ ABS_S32 — the lil HAL component that gives you the absolute value and the vibe check (sign) of your signal 💅

okay bestie, so abs_s32 is a HAL component, and honestly? it's giving "tiny but iconic." 🎀 It takes one number in, and it tells you the absolute value plus a whole lil squad of sign flags on the way out. No cap, it does exactly what it says on the tin.

🦋 SYNOPSIS

loadrt abs_s32 [count=N|names=name1[,name2...]]

Yeah so that's how you load it. You can either ask for count=N copies, or name your own with names=name1[,name2...] — pick your fighter. ✨

🔥 FUNCTIONS

• abs-s32.N — this is the function, and .N is just the instance number, iykyk 🌸

💖 PINS

These are the pins, and this is where it gets good. 🫶

• abs-s32.N.in s32 in — the input value. literally just hand it a number, it's not gonna judge you 🙈
• abs-s32.N.out s32 out — the output value, and it is always non-negative. always. no exceptions, that's the whole point bestie 💅
• abs-s32.N.sign bit out — the sign of the input. false means positive, true means negative. that's it, that's the pin ⭐
• abs-s32.N.is-positive bit out — TRUE if the input is positive, FALSE if the input is 0 or negative. zero is NOT positive, remember that 📌
• abs-s32.N.is-negative bit out — TRUE if the input is negative, FALSE if the input is 0 or positive. same energy, opposite direction 🌈

ok real talk for a sec — notice how 0 fails both "positive" and "negative" checks? that's not a bug, that's just how it's built, and both is-positive and is-negative are FALSE when the input is 0. don't come for me, I'm just the messenger 🧚
