*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`).
