8. List of predefined procedures

These procedures are an integral part of the language definition, and are therefore available on all compilers that fully comply with the standard. From the point of view of how they are calculated, there are four types of predefined procedure in Fortran 90.

• Distributive procedures, operating on a priori scalar arguments, but applicable to arrays; the functions then return an array of the same profile, resulting from the distribution of the function to the elements of the argument(s).

  Example

  ABS (( / – 3 , 2 , 7 / )) gives the vector ( / 3, 2 , 7 /)

• Attribute or query functions, which provide a property of their main argument independently of its value (which may even be indeterminate); they correspond in Ada...
