SELECTED(3F)							  SELECTED(3F)


NAME    [Toc]    [Back]

     - return a	kind type parameter given a decimal exponent range or
     precision.

SYNOPSIS    [Toc]    [Back]

     selected_int_kind (r)

     selected_real_kind	(p,r)

DESCRIPTION    [Toc]    [Back]

     The Fortran 90 transformational function selected_int_kind	returns	the
     kind type parameter of an integer type that can represent the range of
     values n such that	-10**r < n < 10**r.  If	no such	kind exists, the
     result is -1.  If more than one kind meets	the criteria, the result is
     the kind type parameter of	the kind with the smallest decimal exponent
     range. Both r and the result are scalars of integer type.

     The selected_real_kind function is	similar, but returns the kind type
     parameter of a real type that has the decimal precision of	at least p
     digits and	a decimal exponent range of at least r.	 While precision p and
     range r are optional, at least one	of them	must be	specified.  They must
     be	scalar and of integer type.  If	more than one kind satisfies the
     condition,	the result is the kind type parameter of the kind with the
     smallest decimal precision. If a suitable kind is not found, the result
     is:

     -1	  if the requested precision is	unavailable

     -2	  if the requested range is unavailable

     -3	  if both are unavailable
