INSTALL/test_zminMax.f(3)

💖 NAME 💖

Bestie, welcome to the manual page for INSTALL/test_zminMax.f — it's part of the Library Functions Manual, and it's basically a tiny Fortran test with main-character energy for edge cases. ✨

🌸 SYNOPSIS 🌸

Functions/Subroutines

• program zmul — this is the program, and zminMax tests the robustness and precision of the double-valued intrinsic operators MIN and MAX. No cap, it's checking that these operators don't fold under pressure. 💅

🦋 Function/Subroutine Documentation 🦋

program zmul

zminMax tests the robustness and precision of the double-valued intrinsic operators MIN and MAX. That's the whole assignment: throw spicy inputs at MIN and MAX and make sure they behave. 🔥

Here's the test matrix, copied exactly because these pairs are the moment:

           !>
           !> Tests with pairs of numbers (x,y):
           !> Inf inputs where x < y:
           !>    (1) (-Inf,   0)
           !>    (2) ( 0  , Inf)
           !>    (3) (-Inf, Inf)
           !> Inf inputs where x > y:
           !>    (4) ( 0  ,-Inf)
           !>    (5) ( Inf,   0)
           !>    (6) ( Inf,-Inf)
           !> NaN inputs to test NaN propagation:
           !>    (7) ( 0  , NaN)
           !>    (8) ( NaN,   0)
           !> The program tests MIN(x,y) and MAX(x,y) for every pair
           !>
           !>

So yeah: eight pairs total, split into infinity drama and NaN-propagation drama. It runs MIN(x,y) and MAX(x,y) on every single pair — no skipping, no shortcuts, fr fr. 💀

Sign-off, bestie: source/version is LAPACK Version 3.12.0, the page is INSTALL/test_zminMax.f(3), and the footer didn't list a date — so we're not making one up. 🎀💜
