   Introduction
   ------------

   BNC is a high-precision (in this case, 151 digits) floating point calculator.
   It supports the following operators:

   Unary: +,-,! (factorial)

   Binary: +,-,*,/,^

   All unary operators are prefix. For example: 
 
   !4 , +x/4, -33*(3-3).

   The binary operators are right-associative. Thus

   3^2^5=+1.853020188851841E+15
   (3^(2^5))=+1.853020188851841E+15
   ((3^2)^5)=+5.9049E+4

   The operator hierarchy is :

   + - (binary)
   * /
   ^
   ! + - (unary)

   BNC.EXE was written with Borland C++ Builder 1.0 under Windows 95 (so
   it is a 32-bit executable).
   It uses a multiple-precision floating point library for C++ written by
   me, which enables use of virtually all available memory to store numbers.
   It is not , however, arbitrary-precision as in Mathematica or related 
   software.
