Assigning scalars

Function: void ap_scalar_set (ap_scalar_t* rop, ap_scalar_t* op)
Set the value of rop from op.

Function: void ap_scalar_set_mpq (ap_scalar_t* rop, mpq_t mpq)
Function: void ap_scalar_set_int (ap_scalar_t* rop, long int i)

Function: void ap_scalar_set_frac (ap_scalar_t* rop, long int i, unsigned long int j)
Change the type of rop to MPQ and set its value to resp. mpq, i, and i/j.

Function: void ap_scalar_set_double (ap_scalar_t* rop, double k)
Change the type of rop to DOUBLE and set its value to k.

Function: void ap_scalar_set_infty (ap_scalar_t* rop, int sgn)
Set the value of rop to sgn*infinity. Keep the type of the rop.

Function: ap_scalar_t* ap_scalar_alloc_set (ap_scalar_t* op)
Function: ap_scalar_t* ap_scalar_alloc_set_mpq (mpq_t mpq)
Function: ap_scalar_t* ap_scalar_alloc_set_double (double k)
Combined allocation and assignement.
