error in
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
error in does not contain an error 
error in contains an error 


If no error occurred before the node runs, the node begins execution normally. If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out. 
If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out. 
Default: No error
threshold
Level at which the node removes the trailing elements from the numerator and denominator of the quotient of two polynomials.
The node removes the trailing elements whose absolute values or relative values are less than or equal to threshold. If all the elements in the numerator and denominator of the quotient of two polynomials are less than or equal to threshold, g(x) numerator and g(x) denominator return a oneelement array.
Default: 0
threshold type
Method this node uses to remove the trailing elements from the numerator and denominator of the quotient of two polynomials.

Description 
Absolute Value 
0

Relative Value 
1 
Removes the trailing elements whose absolute values are less than or equal to threshold * a, where a is the coefficient that has the maximum absolute value in the numerator and denominator of the quotient of two polynomials. 
Default: Absolute Value
g(x) numerator

Algorithm for Dividing Rational Polynomials
This node uses the following equation to divide one rational polynomial by another:
$g\left(x\right)=\frac{p\left(x\right)}{q\left(x\right)}=\frac{{p}_{n}\left(x\right)\text{\hspace{0.17em}}/\text{\hspace{0.17em}}{p}_{d}\left(x\right)}{{q}_{n}\left(x\right)\text{\hspace{0.17em}}/\text{\hspace{0.17em}}{q}_{d}\left(x\right)}=\frac{{p}_{n}\left(x\right){q}_{d}\left(x\right)}{{p}_{d}\left(x\right){q}_{n}\left(x\right)}$
where
 g(x) is the quotient of p(x) and q(x)
 p(x) is the first rational polynomial
 q(x) is the second rational polynomial
 p_{n}(x) is the numerator polynomial of p(x)
 q_{n}(x) is the numerator polynomial of q(x)
 p_{d}(x) is the denominator polynomial of p(x)
 q_{d}(x) is the denominator polynomial of q(x)
