[ADMB Users] Invoking library qfclib.h

[John Sibert]

Hmm. I'm not sure which OS your are using, but in my world double 
round(double) requires only one argument, not two as in your report 
section example. It is part of the standard C/C++ math library and is 
not an ADMB function.

The " error: cannot convert 'param_init_bounded_number' to 'double' for 
argument '1' to 'double round(double)' " can probably be eliminated by

report << "FPSFpD=" << round(value(FPSFpD)) << endl;

The value function returns the double part of the variable, and there is 
only one argument to round.

However, the example uses the round function on a nested function - I guess to show how versatile it is, but I'm not interested in what those nested functions.
