// get nearest point index of second input
int np = nearpoint(1, @P);

// get that point's position
vector np_pos = point(1, 'P', np);

// measure distance
float dist = distance(@P, np_pos);

// normalise distance
dist = fit(dist, ch('in_min'), ch('in_max'), ch('out_min'), ch('out_max'));

// remap with ramp
dist = chramp('remap', dist);

// set attribute
f@dist = dist;

Thank you
