Usage
Syntax: vectorlen(array v);
Returns the magnitude of vector v.
Explanation
Vectors are often written as <x,y,z>, however in Graal they are written as arrays and often use these syntaxes: {x, y, z} or {x, y}.
What vectordist does, is that it calculates the magnitude of vector v using the following calculation:
magnitude = √(v1² + v2² + v3²)
magnitude = (v[0]^2 + v[1]^2 + v[2]^2)^0.5
Example
function onCreated() {
temp.u = {1, 7, 1};
temp.magnitude = vectordist(v);
}... Will set temp.magnitude to 7.141428428 (√51).
