WARNING!!! IT IS C++ but it uses domath ant rootBase LIBRARY, SOE I CAN MAKE SQARE ROOTS, AND OTHEr STUFF LIKE SIN, COS!!!!!!

#include <iostream>
#include <cstdio>
#include <h.2>
#include <time>
#include <math>
#include <domath>
#include <rootBase>

Then my code doesn't have any error (by the way I'm doing scientific calculator with squared root, line graphing, sin, cos, etc..) but then ...

My debbuger finds problem here:

if(math1 !== math2);
    MathCouldNotReadVoid2();

Which goes to void:

void MathCouldNotReadVoid2();
{
     if(math1 ==! (math3 - math2))
          {
          float decimalpoint();
          using namespace std;
          using namespace fc;
          SquaredRoot();
          float SquaredRootExponents(0.07839947388);
          float SquaredRootExponentFormForRootFormula((SquaredRootExponents *==)+ PiV);
          float SqRootFormulaStepOnePISHORTCUT(>=3.14'>DoMath<'<=7.2 * FgYt2 + 7.1107);
          }
     else main();
 }

That's the only one of my couple steps, for SquaredRoot, but it doesn't define the ">=3.14'>DoMath<'<=7.2*FgYt2+7.1107" step. I know some people may not know this type of "command" from the 'rootBase' library, but maybe some of you may know... Please help...Thanks.
