   Alternatively, you can use the oldest scientific programming   
   language, Fortran.   
      
   Fortran lets you declare a real variable with at least   
   n valid decimal digits, and common compilers (ifort and   
   gfortran, among others) allow up to IEEE 128 bit numbers,   
   with 33 valid digits.  This is described in Michael   
   Metcalf's Wikiedia article on Fortran 95 features under   
   https://en.wikipedia.org/wiki/Fortran_95_language_features#REAL .
