💖 la_xisnan — bestie, it's the NaN detector era 💖

okay so this is a page from the LAPACK manual, section 3, and it's all about la_xisnan 🦋 the little module that answers the one question we all need answered at 3am: is this number a NaN or not 💅

✨ NAME ✨

la_xisnan — the module whose whole personality is "is it NaN tho" 🙈

🌸 SYNOPSIS 🌸

🎀 Data Types 🎀

  • interface la_isnan — the interface doing the actual vibes ✨

🎀 Functions/Subroutines 🎀

  • logical function disnan (x)

👑 Function/Subroutine Documentation 👑

💜 logical function la_xisnan::disnan (real(wp) x)

Definition at line 35 of file la_xisnan.F90. 📄✨

💜 logical function la_xisnan::sisnan (real(wp) x)

Definition at line 11 of file la_xisnan.F90. 📄✨

lowkey iconic that both of these live in the same file and they're just the double and single precision versions of the same energy 🫶 the module hands you la_isnan as an interface, and then sisnan and disnan do the actual work. no cap.
