FUNCTION::FP_TO_LONG(3stap)

💖 FUNCTION::FP_TO_LONG 💖

okay bestie, so this one lives in the SystemTap Tapset Reference, section 3stap, and it's literally the glow-up machine that takes your floating point and hands you back an int64. no cap. 🦋

---

✨ NAME ✨

function::fp_to_long — Convert fp to int64 💅

---

🌸 SYNOPSIS 🌸

fp_to_long:long(infp:long,roundingMode:long,exact:long)

---

🎀 ARGUMENTS 🎀

• infp — the 64 bit floating point stored in long. that's the lil guy we're converting, periodt. 🍓
• roundingMode — through 0-6, which are round to nearest even, minMag, min, max, near maxMag and round to odd. pick your fighter, she does all seven. 😭
• exact — the boolean value, if exact is 1 than raising inexact exception, otherwise ignore the exception. so like, 1 = we're dramatic about it, 0 = we're chill. 🙈

---

💜 DESCRIPTION 💜

Given a 64 bit floating point, which is stored in long, use the long value to initiate self-defined float64_t type, then apply the f64_to_i64 function to get the string representation. so it's giving "build the float64_t, run f64_to_i64, get the string rep" — a whole three-step main character arc and honestly? iconic. 👑
