Adding zero to shift indexes

[Scott]

Can someone please explain the purpose of adding zero to the "shift" in instances like those in the code below, or point me in the right direction to find out why/when this is required?

double mySAR = iSAR(NULL, PERIOD_H4, 0.02, 0.2, index + 0);

versus

double mySAR = iSAR(NULL, PERIOD_H4, 0.02, 0.2, index);

Why add zero?

It does nothing.

Someone was probably testing with other values, like 1 2 3, whatever.

Thanks very much for the prompt reply - - and clarifying the situation. It did seem odd.

Have a great day.
