INTBITSTOFLOAT(3G)

💖 INTBITSTOFLOAT — the 3G girlies' guide 💖

okay so bestie, we're in section 3G of the manual and today's main character is intBitsToFloat (and its understudy _uintBitsToFloat, we love her too). 🎀

---

✨ NAME ✨

intBitsToFloat, _uintBitsToFloat — produce a floating point using an encoding supplied as an integer

---

🌸 DECLARATION 🌸

no cap, here's the signature, copy it exactly bestie:

genType intBitsToFloat(genIType x);

genType uintBitsToFloat(genUType x);

---

🦋 PARAMETERS 🦋

• x — Specifies the bit encoding to return as a floating point value. it's giving "here's some bits, now make them a float" 💅

---

💜 DESCRIPTION 💜

so intBitsToFloat and uintBitsToFloat return the encoding you passed in parameter x as a floating-point value. that's the whole vibe. you hand over bits, you get back a float. iconic. ✨

now listen closely because this part matters:

• If the encoding of a NaN is passed in x, it will not signal and the resulting value will be undefined. 😭 undefined behaviour, bestie, that's the "we don't know what happens" zone, tread carefully.
• If the encoding of a floating point infinity is passed in parameter x, the resulting floating-point value is the corresponding (positive or negative) floating point infinity. ♾️ so that one's actually well-behaved.

👑 VERSION SUPPORT 👑

here's the vibe check on which OpenGL Shading Language Versions are serving for the function name intBitsToFloat:

• intBitsToFloat:
  • OpenGL Shading Language Version 1.10 — - (nope, not yet 🚫)
  • OpenGL Shading Language Version 1.20 — - 🚫
  • OpenGL Shading Language Version 1.30 — - 🚫
  • OpenGL Shading Language Version 1.40 — - 🚫
  • OpenGL Shading Language Version 1.50 — - 🚫
  • OpenGL Shading Language Version 3.30 — ✔ ✅
  • OpenGL Shading Language Version 4.00 — ✔ ✅
  • OpenGL Shading Language Version 4.10 — ✔ ✅
  • OpenGL Shading Language Version 4.20 — ✔ ✅
  • OpenGL Shading Language Version 4.30 — ✔ ✅
  • OpenGL Shading Language Version 4.40 — ✔ ✅
  • OpenGL Shading Language Version 4.50 — ✔ ✅

so basically she showed up in 3.30 and has been that girl ever since. 🌈

okay that's the whole page bestie, you ate that 💅✨ and just so you know where this came from: this was the [FIXME: source] situation, dated 01/03/2018, filed under INTBITSTOFLOAT(3G). slay, go forth and cast those bits 🎀🦋💖
