The point biserial is just a Pearson Product Moment correlation. It's distinction is just a hold-over from the old days before computers made it easy to compute correlations. It's formula is a littler simpler to compute on a had calculator but just do a Pearson on the data (assuming the binary variable is numeric (i.e. 0,1) to get it.
