a

Values at which the node evaluates the polynomial.

This input accepts the following data types:

  • Double-precision, floating-point number
  • Complex double-precision, floating-point number
  • 1D array of double-precision, floating-point numbers
  • 1D array of complex double-precision, floating-point numbers

numerator

Numerator coefficients, in ascending order of power, of the rational polynomial.

This input accepts the following data types:

  • 1D array of double-precision, floating-point numbers
  • 1D array of complex double-precision, floating-point numbers
datatype_icon

denominator

Denominator coefficients, in ascending order of power, of the rational polynomial.

This input accepts the following data types:

  • 1D array of double-precision, floating-point numbers
  • 1D array of complex double-precision, floating-point numbers

error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

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

polynomial evaluation

Result of evaluating the rational polynomial at a.

This output can return the following data types:

  • Double-precision, floating-point number
  • Complex double-precision, floating-point number
  • 1D array of double-precision, floating-point numbers
  • 1D array of complex double-precision, floating-point numbers

error out

Error information.

The node produces this output according to standard error behavior.
