Computes the dilogarithm function, or Spence's Integral.
A real nonnegative number. If x is negative, the node uses the absolute value of x.
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.
Default: No error
Value of the dilogarithm function.
Error information.
The node produces this output according to standard error behavior.

The following equation defines the dilogarithm function and Spence's Integral.
where $F\left(x\right)$ is Spence's Integral and $di\mathrm{ln}\left(x\right)$ is the dilogarithm function.
The following intervals for the input values define the dilogarithm function.
The function is defined for nonnegative real values of x.
