I have a function to return points along a line and my return comes back with two decimal points...? For example, a return of my variable px will be something like -88.4029.032940598.

vx is the x vector and mult is the distance of the line plus distance to calculate the point. Here is the operation that is returning these values:

var mult = parseFloat(mag + theUnit);
var px = coord_one.x_point + (vx * mult);
console.log(px);

Never have seen this before- I appreciate any and all help!
