 A.5.3 Floating Type Macros
 --------------------------
 
 The specific representation of floating point numbers varies from
 machine to machine.  Because floating point numbers are represented
 internally as approximate quantities, algorithms for manipulating
 floating point data often need to take account of the precise details of
 the machine's floating point representation.
 
    Some of the functions in the C library itself need this information;
 for example, the algorithms for printing and reading floating point
 numbers ( I/O on Streams) and for calculating trigonometric and
 irrational functions ( Mathematics) use it to avoid round-off
 error and loss of accuracy.  User programs that implement numerical
 analysis techniques also often need this information in order to
 minimize or compute error bounds.
 
    The header file 'float.h' describes the format used by your machine.
