SRC/dladiv.f(3)

okay bestie, welcome to the Library Functions Manual page for SRC/dladiv.f(3) — we're doing complex division in real arithmetic and we're gonna make it make sense 💖

🌸 NAME 🌸

SRC/dladiv.f

🦋 SYNOPSIS 🦋

Functions/Subroutines

• subroutine dladiv (a, b, c, d, p, q) — DLADIV performs complex division in real arithmetic, avoiding unnecessary overflow. ✨
• subroutine dladiv1 (a, b, c, d, p, q)
• double precision function dladiv2 (a, b, c, d, r, t)

👑 Function/Subroutine Documentation 👑

💖 subroutine dladiv (double precision a, double precision b, double precision c, double precision d, double precision p, double precision q) 💖

DLADIV performs complex division in real arithmetic, avoiding unnecessary overflow.

✨ Purpose ✨

okay so here's the whole vibe, straight from the source:

!>
!> DLADIV performs complex division in  real arithmetic
!>
!>                       a + i*b
!>            p + i*q = ---------
!>                       c + i*d
!>
!> The algorithm is due to Michael Baudin and Robert L. Smith
!> and can be found in the paper
!>
!>

the algorithm is due to Michael Baudin and Robert L. Smith, and the source says it can be found in the paper — that's literally all the citation we get here, bestie 🫶
