## AssertEqualsNumericalPoly

Compares two numerical polynomials

### Syntax

$apcocoa/ts/assert.AssertEqualsNumericalPoly(Result: POLY, Expected: POLY, Eps: RAT, ErrMsg: STRING)

### Description

This function compares two numerical polynomials F:='Result' and G:='Expected'. The sum over the absolute values of the coefficients of F-G must be smaller than epsilon 'Eps'. If the polynomials are numerically not the same it throws an error and prints the error message 'ErrMsg'.

@param

*Result*: The first numerical polynomial@param

*Expected*: The second numerical polynomial@param

*Eps*: Epsilon@param

*ErrMsg*: Error Message

#### Example

F := 0.212*x + 2.103*xy; G := 0.00001*x^2 + 0.214*x + 2.1*xy; $apcocoa/ts/assert.AssertEqualsNumericalPoly(F,G,0.1,"Polynomials are numerically not the same."); -- throws no error => test passed F := 0.212*x + 2.103*xy; E := 0.00001*x^2 + 0.214*x + 2*xy; $apcocoa/ts/assert.AssertEqualsNumericalPoly(F,G,00.1,"Polynomials are numerically not the same."); -- throws an error => test not passed
