DISNAN(3)

💅 DISNAN(3) — Library Functions Manual 💅

okay so bestie, gather round, because we're talking about DISNAN today and honestly? she's a tiny little icon and she knows it 🎀

The page lives at /home/abui...RC/disnan.f(3), which is also the name up top — that's just where the manpage hangs out, don't worry about it ✨

✨ NAME ✨

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

yeah that's the whole name, it's a whole path, she's extra like that 💅 (blame the build system, not her)

🦋 SYNOPSIS 🦋

Functions/Subroutines

logical function DISNAN (din)

DISNAN tests input for NaN. that's it. that's the gig. no cap 🔥

---

🌸 Function/Subroutine Documentation 🌸

logical function DISNAN (double precision, intent(in) din)

DISNAN tests input for NaN. (yes, again — she's consistent, we love that for her 💖)

👑 Purpose:

!>
!> DISNAN returns .TRUE. if its argument is NaN, and .FALSE.
!> otherwise.  To be replaced by the Fortran 2003 intrinsic in the
!> future.
!>

so like — feed her a NaN, she says .TRUE. ✨ feed her literally anything else, she says .FALSE. 💀 that's the entire vibe check. and bestie, heads up: to be replaced by the Fortran 2003 intrinsic in the future — so she's lowkey on her way out, an icon in her retirement era 🫶 still serving though!

🧚 Parameters

• DIN — DIN is DOUBLE PRECISION. this is the input to test for NaN. that's the one and only thing she needs from you 🍓

!>          DIN is DOUBLE PRECISION
!>          Input to test for NaN.

💀 gentle reminder bestie: the .TRUE./.FALSE. thing is literally the whole function — NaN in, .TRUE. out, everything else in, .FALSE. out. don't overthink her, she's small but mighty 🎀

and that's the whole page!! mwah 💖 this manual page, disnan.f(3) — LAPACK Version 3.12.0, dated /home/abui...RC/disnan.f(3) — was brought to you by the letter D, the number 58, and one (1) extremely overqualified Fortran subroutine. slay, periodt ✨🦋👑
