| class | IG.Num.Func | 
|  | Creation of a number of standard real mathematical functions in one dimension. Conttains subclasses for specific functions ans corresponding static creator methods. Creator methods come in 3 different version: for reference form of the function (e.g. just Exp[x]), for form shifted and stretched in x direction, and general form shifted and stretched in both directions.

| class | IG.Num.Func.Linear | 
|  | Linear function, f(x) = a1*x + a0. Specific properties: Zero - returns a zero. HasZero - either the function has a zero or not.  More...

| class | IG.Num.Func.Quadratic | 
|  | Quadratic function, f(x) = a2*x*x + a1*x + a0. Specific properties: Zero - returns a zero. Zero1 - returns the fierst zero. Zero2 - returns the second zero. NumZeros - 0, 1 or 2, returns number of zeros. HasZero - either the function has a zero or not.  More...

| class | IG.Num.Func.Cubic | 
|  | Cubic function, f(x) = a3*x*x*x + a2*x*x + a1*x + a0. Specific properties: Zero - returns a zero. Zero1 - returns the fierst zero. Zero2 - returns the second zero. Zero3 - returns the third zero. NumZeros - returns number of zeros (0, 1 or 3). HasZero - either the function has a zero or not. Min - returns function's strict minimum. Max - returns function's strict maximum.  More...
