SYNOPSIS

elemental real function f2c(fahrenheit)
     class(*),intent(in) :: fahrenheit

DESCRIPTION

Converts Fahrenheit temperatures to Celsius using the formula:
    celsius=(fahrenheit+40.0)*5.0/9.0 - 40.0

OPTIONS

fahrenheit
any standard scalar value supported by anyscalar_to_real(3f).

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

Results

With REAL array input -40.0000000 0.00000000 100.000000 With INTEGER array input -40.0000000 0.00000000 100.000000 With DOUBLEPRECISION -40.0000000 0.00000000 100.000000
