SYNOPSIS

impure elemental function dble(string)

    character(len=*) :: string
    integer          :: dble

DESCRIPTION

dble(3f) returns a DOUBLE value when given a numeric representation of a numeric value. This overloads the DBLE(3f) intrinsic so that CHARACTER arguments assumed to represent a numeric value may be input.

OPTIONS

STRING	input string to be converted to a dble value

RETURNS

DBLE	double precision value represented by input string

EXAMPLES

Sample program:

     program demo_dble
     use M_strings, only: dble
     implicit none
     write(*,*)dble(’100’),dble(’20.4’)
     write(*,*)’dble still works’,dble(20),dble(20.4)
     write(*,*)’elemental’,&
     & dble([character(len=23) :: ’10’,’20.3’,’20.5’,’20.6’])
     end program demo_dble
