public static double p00_exact(ref p00Data data, int problem)
//****************************************************************************80
//
// Purpose:
//
// P00_EXACT returns the exact integral for any problem.
//
// Discussion:
//
// This routine provides a "generic" interface to the exact integral
// routines for the various problems, and allows a problem to be called
// by index (PROBLEM) rather than by name.
//
// In most cases, the "exact" value of the integral is not given;
// instead a "respectable" approximation is available.

// Author:

//
// Parameters:
//
// Input, int PROBLEM, the index of the problem.
//
// Output, double P00_EXACT, the exact value of the integral.
