MathLib installed?

Is there a way to find out if MathLib is installed?

The easiest way to tell is by calling a math function. If it returns 0 when it shouldn't, you know MathLib is not there:

if (sqrt(9.0) == 0.0) {
// MathLib not installed
}

When I call a function without MathLib, I get a fatal exception rather than a result of zero. I'm hoping for a more graceful way to see if it's installed.

Thanks, Greg

That's not the intended design :(. Here is another way to detect it.

string name;
DatabaseMgr dbm;
name = dbm.dbenum(true, "libr", "MthL");
if (name == "MathLib") {
// mathlib is installed
}
