SYNOPSIS

function base2(int)

    integer,intent(in)           :: int
    character(len=:),allocatable :: base2

DESCRIPTION

Convert a whole number to a string in base 2.

This is often done with the B edit descriptor and an internal WRITE() statement, but is done without calling the I/O routines, and as a function.

OPTIONS

int	input string representing numeric whole value

RETURNS

base2	string representing input value in base 2

EXAMPLES

Sample program:

     program demo_base2
     use M_strings, only : base2
     implicit none
        write(*,’(a)’) base2(huge(0))
        write(*,’(a)’) base2(0)
        write(*,’(a)’) base2(64)
        write(*,’(a)’) base2(-64)
        write(*,’(a)’) base2(-huge(0)-1)
     end program demo_base2
