Method length

Gets the magnitude of the vector, defined as sqrt(x^2+y^2+z^2). The value of this method is not cached and uses a costly square-root function, so do not repeatedly call this method to get the vector's magnitude. NaN will be returned if the inner result of the sqrt() function overflows, which will be
