##### 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).
