IEEECK(3)

💅 IEEECK(3) — Library Functions Manual ✨

okay bestie, welcome to the Library Functions Manual page for IEEECK. The header path is /home/abui...RC/ieeeck.f(3) — yes, that exact path, keep it. 🫶

🌸 NAME 🌸

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/SRC/ieeeck.f

That's the name/path, no cap. The actual routine is IEEECK, and she's living in that Fortran file. 💖

✨ SYNOPSIS ✨

🦋 Functions/Subroutines 🦋

integer function IEEECK (ispec, zero, one)
    IEEECK

🎀 Function/Subroutine Documentation 🎀

integer function IEEECK (integer ispec, real zero, real one)
    IEEECK

🌈 Purpose 🌈

IEEECK is called from the ILAENV to verify that Infinity and possibly NaN arithmetic is safe (i.e. will not trap). That's the whole assignment, and she ate. 💅

🧾 Parameters 🧾

• ISPEC — this one is an INTEGER. It specifies whether to test just for infinity arithmetic or whether to test for infinity and NaN arithmetic. The values are:
  • = 0: Verify infinity arithmetic only.
  • = 1: Verify infinity and NaN arithmetic.
• ZERO — this one is a REAL. It must contain the value 0.0. It gets passed in to prevent the compiler from optimizing away this code. (Compiler girlies stay lurking, so we feed them a zero. 🙈)
• ONE — this one is a REAL. It must contain the value 1.0. Same deal: it's passed to prevent the compiler from optimizing away this code. 🍓
• RETURN VALUE: INTEGER — the return vibe is:
  • = 0: Arithmetic failed to produce the correct answers.
  • = 1: Arithmetic produced the correct answers.
