Intrinsic Functions

F90 offers efficient implementations for some of the most frequently performed tasks in programming. These implementations are available as functions, built the F90 language, and named ``intrinsics''. For example, taking absolute value can be done by calling the intrinsic function ABS(x). Note that ABS is built in the F90 language (and therefore it is not necessary to include any special header, or link the program to a mathematical library to perform ABS).
