264 The affine coordinates for a point describe a point in terms of its x and y
266 coordinates for the point \fBp\fR defined over the curve given in \fBgroup\fR. The
268 may be \s-1NULL,\s0 to the corresponding coordinates of \fBp\fR.
280 As well as the affine coordinates, a point can alternatively be described in
281 terms of its Jacobian projective coordinates (for Fp curves only). Jacobian
282 projective coordinates are expressed as three values x, y and z. Working in
284 operations. A mapping exists between Jacobian projective coordinates and
285 affine coordinates. A Jacobian projective coordinate (x, y, z) can be written
287 projective from affine coordinates is simple. The coordinate (x, y) is mapped

296 Points can also be described in terms of their compressed coordinates. For a
