std::underflow_error(3)

💖 std::underflow_error 💖

okay bestie, welcome to the manual page for std::underflow_error — she's a Library Functions Manual girlie, page 3, and she is so underrated. pull up a chair, grab a strawberry 🍓, and let's get into it.

---

✨ NAME ✨

std::underflow_error — the exception that shows up when your arithmetic goes too low. yes babe, numbers have a basement and sometimes you fall through the floor 🕳️

---

🌸 SYNOPSIS 🌸

#include <stdexcept_except.h>

she Inherits std::runtime_error. so like… she's part of the runtime_error family, it's giving nepo baby but make it exception hierarchy 💅

---

🎀 Public Member Functions 🎀

here's the whole squad, no gatekeeping:

• underflow_error (const char *) — build one from a C-style string, classic.
• underflow_error (const string &__arg) — build one from a std::string instead, fancy.
• underflow_error (const underflow_error &)=default — copy constructor, defaulted, she can clone herself.
• underflow_error (underflow_error &&)=default — move constructor, defaulted, she can zoom.
• underflow_error & operator= (const underflow_error &)=default — copy assignment, defaulted.
• underflow_error & operator= (underflow_error &&)=default — move assignment, defaulted.
• virtual const char * what () const noexcept — the iconic one. returns the message. never throws. periodt.

---

🦋 Detailed Description 🦋

Thrown to indicate arithmetic underflow.

that's the whole vibe. if a computation underflows, this is the girl who gets thrown. 🔥

💜 Member Function Documentation 💜

virtual const char * std::runtime_error::what () const [virtual], [noexcept], [inherited]

okay so this one is inherited, meaning she got it from std::runtime_error, and it's marked [virtual] and [noexcept] — so she's flexible and she will never, ever throw at you. icon behaviour.

what she does: returns a C-style character string describing the general cause of the current error — literally the same string that got passed to the ctor. so whatever you told her when you made her, that's what she says back. no plot twists.

• Reimplemented from std::exception.
• Reimplemented in std::experimental::filesystem::v1::filesystem_error, std::filesystem::filesystem_error, and std::ios_base::failure.
• References what().
• Referenced by what().

(yes she references herself and gets referenced by herself. main character energy, honestly. she's in a lil recursive situationship with her own documentation. 🙈)

Generated automatically by Doxygen for libstdc++ from the source code. so technically nobody wrote her, she just kinda materialized. a queen who was born, not made. 👑

and that's the page, bestie!! 🫶 go forth and catch your underflows responsibly, and remember: if your number goes below where it should, std::underflow_error is right there waiting. slay 💖
