private function d2s(dvalue, fmt) result(outstr)

NAME

  v2s(3f) - [M_strings:TYPE] return numeric string from a numeric value
  (LICENSE:PD)

SYNOPSIS

   function v2s(value) result(outstr)

    integer|real|doubleprecision|logical,intent(in ) :: value
    character(len=:),allocatable :: outstr
    character(len=*),optional,intent(in) :: fmt

DESCRIPTION

v2s(3f) returns a representation of a numeric value as a
string when given a numeric value of type REAL, DOUBLEPRECISION,
INTEGER or LOGICAL. It creates the strings using internal WRITE()
statements. Trailing zeros are removed from non-zero values, and the
string is left-justified.

OPTIONS

VALUE   input value to be converted to a string
FMT     format can be explicitly given, but is limited to
        generating a string of eighty or less characters.

RETURNS

OUTSTR  returned string representing input value,

EXAMPLE

Sample Program:

program demo_v2s
use M_strings, only: v2s
write(*,*) 'The value of 3.0/4.0 is ['//v2s(3.0/4.0)//']'
write(*,*) 'The value of 1234    is ['//v2s(1234)//']'
write(*,*) 'The value of 0d0     is ['//v2s(0d0)//']'
write(*,*) 'The value of .false. is ['//v2s(.false.)//']'
write(*,*) 'The value of .true. is  ['//v2s(.true.)//']'
end program demo_v2s

Expected output

 The value of 3.0/4.0 is [0.75]
 The value of 1234    is [1234]
 The value of 0d0     is [0]
 The value of .false. is [F]
 The value of .true. is  [T]
