cmath(3)

💖 NAME

okay so bestie, this is cmath(3) from the Library Functions Manual — the libstdc++ page for cmath. The original NAME line is just cmath with no extra desc, so that's the vibe. slay 💅

💅 Detailed Description

Okay so real talk, bestie: this is a Standard C++ Library file. You should include this file in your programs, rather than any of the *.h implementation files. periodt 💜

This is the C++ version of the Standard C Library header math.h, and its contents are (mostly) the same as that header, but are all contained in the std namespace (except for names which are defined as macros in C). iykyk ✨
