EXAMPLE

Sample program

   program demo_f2c
   use M_units, only :  f2c
   implicit none
      write(*,*)’With REAL array input    ’, f2c([ -40.0,32.0, 212.0 ])
      write(*,*)’With INTEGER array input ’, f2c([ -40,  32,   212   ])
      write(*,*)’With DOUBLEPRECISION     ’, f2c(-40.0d0),f2c(32.0d0),f2c(212.0d0)
   end program demo_f2c
