Inputs/Outputs

  • cdbl.png x —

    x is the input argument. If x is negative, the VI uses the absolute value of x.

  • idbl.png diln(x) —

    diln(x) returns the value of the dilogarithm function.

    • The following equation defines the dilogarithm and the Spence's Integral.

    where F(x) is the Spence's Integral and diln(x) is the dilogarithm.

    The following intervals for the input values define the dilogarithm function.

    The function is defined for nonnegative real values of x.
