Dense output for the Prince-Dormand 8(7) (RK8(7)13M) method rkdp87. This is an interpolant of order 8 constructed by P. Stone, which requires 8 additional function evaluations (see rkdp87_dense_extra_stages).
Note
The interpolant is published in the polynomial form. Here it has been
converted (exactly, using high precision arithmetic)
to the form used in DOPRI5 and DOP853 (see dense_coefficients), which has
much smaller roundoff error for these coefficients. This code is generated by
scripts/generate_dense.py.
