There are several ways:

include/llvm/ADT/APInt.h


   /// toString - Converts an APInt to a string and append it to Str. 
Str is
   /// commonly a SmallString.
   void toString(SmallVectorImpl<char> &Str, unsigned Radix, bool Signed,
                 bool formatAsCLiteral = false) const;

   /// Considers the APInt to be unsigned and converts it into a string 
in the
   /// radix given. The radix can be 2, 8, 10 16, or 36.
   void toStringUnsigned(SmallVectorImpl<char> &Str, unsigned Radix = 
10) const {
     toString(Str, Radix, false, false);
   }

   /// Considers the APInt to be signed and converts it into a string in the
   /// radix given. The radix can be 2, 8, 10, 16, or 36.
   void toStringSigned(SmallVectorImpl<char> &Str, unsigned Radix = 10) 
const {
     toString(Str, Radix, true, false);
   }

   /// toString - This returns the APInt as a std::string.  Note that 
this is an
   /// inefficient method.  It is better to pass in a 
SmallVector/SmallString
   /// to the methods above to avoid thrashing the heap for the string.
   std::string toString(unsigned Radix, bool Signed) const;
