+.SH DESCRIPTION
+.IX Header "DESCRIPTION"
+EC_POINT_add adds the two points \fBa\fR and \fBb\fR and places the result in \fBr\fR. Similarly EC_POINT_dbl doubles the point \fBa\fR and places the
+result in \fBr\fR. In both cases it is valid for \fBr\fR to be one of \fBa\fR or \fBb\fR.
+.PP
+EC_POINT_invert calculates the inverse of the supplied point \fBa\fR. The result is placed back in \fBa\fR.
+.PP
+The function EC_POINT_is_at_infinity tests whether the supplied point is at infinity or not.
+.PP
+EC_POINT_is_on_curve tests whether the supplied point is on the curve or not.
+.PP
+EC_POINT_cmp compares the two supplied points and tests whether or not they are equal.
+.PP
+The functions EC_POINT_make_affine and EC_POINTs_make_affine force the internal representation of the EC_POINT(s) into the affine
+coordinate system. In the case of EC_POINTs_make_affine the value \fBnum\fR provides the number of points in the array \fBpoints\fR to be
+forced. These functions were deprecated in OpenSSL 3.0 and should no longer be used.
+Modern versions automatically perform this conversion when needed.
+.PP
+EC_POINT_mul calculates the value generator * \fBn\fR + \fBq\fR * \fBm\fR and stores the result in \fBr\fR.
+The value \fBn\fR may be NULL in which case the result is just \fBq\fR * \fBm\fR (variable point multiplication). Alternatively, both \fBq\fR and \fBm\fR may be NULL, and \fBn\fR non-NULL, in which case the result is just generator * \fBn\fR (fixed point multiplication).
+When performing a single fixed or variable point multiplication, the underlying implementation uses a constant time algorithm, when the input scalar (either \fBn\fR or \fBm\fR) is in the range [0, ec_group_order).
+.PP
+Although deprecated in OpenSSL 3.0 and should no longer be used,
+EC_POINTs_mul calculates the value generator * \fBn\fR + \fBq[0]\fR * \fBm[0]\fR + ... + \fBq[num\-1]\fR * \fBm[num\-1]\fR. As for EC_POINT_mul the value \fBn\fR may be NULL or \fBnum\fR may be zero.
+When performing a fixed point multiplication (\fBn\fR is non-NULL and \fBnum\fR is 0) or a variable point multiplication (\fBn\fR is NULL and \fBnum\fR is 1), the underlying implementation uses a constant time algorithm, when the input scalar (either \fBn\fR or \fBm[0]\fR) is in the range [0, ec_group_order).
+Modern versions should instead use \fBEC_POINT_mul()\fR, combined (if needed) with \fBEC_POINT_add()\fR in such rare circumstances.
+.PP
+The function EC_GROUP_precompute_mult stores multiples of the generator for faster point multiplication, whilst
+EC_GROUP_have_precompute_mult tests whether precomputation has already been done. See \fBEC_GROUP_copy\fR\|(3) for information
+about the generator. Precomputation functionality was deprecated in OpenSSL 3.0.
+Users of \fBEC_GROUP_precompute_mult()\fR and \fBEC_GROUP_have_precompute_mult()\fR should
+switch to named curves which OpenSSL has hardcoded lookup tables for.
+.SH "RETURN VALUES"
+.IX Header "RETURN VALUES"
+The following functions return 1 on success or 0 on error: EC_POINT_add, EC_POINT_dbl, EC_POINT_invert, EC_POINT_make_affine,
+EC_POINTs_make_affine, EC_POINTs_make_affine, EC_POINT_mul, EC_POINTs_mul and EC_GROUP_precompute_mult.
+.PP
+EC_POINT_is_at_infinity returns 1 if the point is at infinity, or 0 otherwise.
+.PP
+EC_POINT_is_on_curve returns 1 if the point is on the curve, 0 if not, or \-1 on error.
+.PP
+EC_POINT_cmp returns 1 if the points are not equal, 0 if they are, or \-1 on error.
+.PP
+EC_GROUP_have_precompute_mult return 1 if a precomputation has been done, or 0 if not.
