Sine Integral (G Dataflow)

    Last Modified: January 9, 2017

    Evaluates the sine integral for any real nonnegative number.



    A real nonnegative number.


    error in

    Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.

    Default: No error



    Result of the calculation of the sine integral for the given value of x.


    error out

    Error information. The node produces this output according to standard error behavior.

    Algorithm for Evaluating the Sine Integral

    The following equation defines the sine integral.

    S i ( x ) = 0 x sin ( t ) t d t

    The following illustration shows the graph of the sine integral in the interval (0, 15).

    Where This Node Can Run:

    Desktop OS: Windows

    FPGA: Not supported
