// The floating point precision of the class library as a whole is controlled
// by this typedefn statement.

typedef double REAL;

// If this symbol is defined then the library will carry out extra error
// checking such as some array bounds checking. This checking will obviously
// make the library more robust but will also increase excecution times. Simply
// comment this out if the extra checking is not required.

#define DEBUG_VERSION

// These macros can be used for simple debugging and run time error messages.
// They simply print the line and file where it is called and the value of the
// given variable. In the case of FATAL_ERROR and WARNING this variable should
// be a message giving some information concerning the problem. The FATAL_ERROR
// macro causes the immediate termination of the program and should only be used
// for serious problems.
//
// These macros will be put into their own namespace when this language feature
// is more widely implemented.
