public const int VEC3_LEN

Evaluates to the number of components of a Vec3.

This symbol is useful when declaring a C array of floating point values to be used with init_from_float and to_float, e.g.

  float v[GRAPHENE_VEC3_LEN];

// vec is defined elsewhere
graphene_vec3_to_float (&vec, v);

for (int i = 0; i < GRAPHENE_VEC2_LEN; i++)
fprintf (stdout, "component %d: %g\n", i, v[i]);
