SYNOPSIS

       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,

EXAMPLES

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]
