This major node describes @command{awk}'s built-in functions, which fall into three categories: numeric, string, and I/O. @command{gawk} provides additional groups of functions to work with values that represent time, do bit manipulation, and to internationalize and localize programs.
Besides the built-in functions, @command{awk} has provisions for writing new functions that the rest of a program can use. The second half of this major node describes these user-defined functions.
