188 The affine coordinates for a point describe a point in terms of its x and y
190 coordinates for the point \fBp\fR defined over the curve given in \fBgroup\fR. The
192 may be NULL, to the corresponding coordinates of \fBp\fR.
204 As well as the affine coordinates, a point can alternatively be described in
205 terms of its Jacobian projective coordinates (for Fp curves only). Jacobian
206 projective coordinates are expressed as three values x, y and z. Working in
208 operations.  A mapping exists between Jacobian projective coordinates and
209 affine coordinates. A Jacobian projective coordinate (x, y, z) can be written
211 projective from affine coordinates is simple. The coordinate (x, y) is mapped
213 to set or get the projective coordinates in older versions use
220 Points can also be described in terms of their compressed coordinates. For a
