Use a while loop instead in your main script:-
Code:
while read value
do
    ./c2f.ss $value
    echo $value
done < $input_file

Accept the argument passed in your c2f.ss script & do the math:-
Code:
c=$1
f=$(echo $c / 5 \* 9 + 32 | bc -l);
echo $c "=" ${f%%.*} >> ans.file

Also make sure your script c2f.ss is executable:-
Code:
chmod +x c2f.ss

sla_lin_berr.f

sla_lin_berr.f(3)						      LAPACK							 sla_lin_berr.f(3)

NAME

       sla_lin_berr.f -

SYNOPSIS

   Functions/Subroutines
       subroutine sla_lin_berr (N, NZ, NRHS, RES, AYB, BERR)
	   SLA_LIN_BERR

Function/Subroutine Documentation
   subroutine sla_lin_berr (integerN, integerNZ, integerNRHS, real, dimension( n, nrhs )RES, real, dimension( n, nrhs )AYB, real, dimension( nrhs
       )BERR)
       SLA_LIN_BERR

       Purpose:

	       SLA_LIN_BERR computes componentwise relative backward error from
	       the formula
		   max(i) ( abs(R(i)) / ( abs(op(A_s))*abs(Y) + abs(B_s) )(i) )
	       where abs(Z) is the componentwise absolute value of the matrix
	       or vector Z.

       Parameters:
	   N

		     N is INTEGER
		The number of linear equations, i.e., the order of the
		matrix A.  N >= 0.

	   NZ

		     NZ is INTEGER
		We add (NZ+1)*SLAMCH( 'Safe minimum' ) to R(i) in the numerator to
		guard against spuriously zero residuals. Default value is N.

	   NRHS

		     NRHS is INTEGER
		The number of right hand sides, i.e., the number of columns
		of the matrices AYB, RES, and BERR.  NRHS >= 0.

	   RES

		     RES is REAL array, dimension (N,NRHS)
		The residual matrix, i.e., the matrix R in the relative backward
		error formula above.

	   AYB

		     AYB is REAL array, dimension (N, NRHS)
		The denominator in the relative backward error formula above, i.e.,
		the matrix abs(op(A_s))*abs(Y) + abs(B_s). The matrices A, Y, and B
		are from iterative refinement (see sla_gerfsx_extended.f).

	   BERR

		     BERR is REAL array, dimension (NRHS)
		The componentwise relative backward error from the formula above.
