• Scl<MPZ> which corresponds to big integers, based on the GMP type mpz.
  
  
• Scl<MPQ> which corresponds to big rational, based on the GMP type mpq.
  
  
• Scl<MPF> which corresponds to big floats, based on the GMP type mpf.
  
  
• Scl<MPFR> which corresponds to reliable big floats, based on the MPFR library.
  
  
• Scl<MPC> which corresponds to big complexes, based on the type mpc.

Example
