equalWithAbsError(m: V4i, e: int) → bool

Compare two vectors and test if they are “approximately equal”: Return True if the coefficients of this and m are the same with an absolute error of no more than e, i.e., for all i, j:

abs (this[i][j] - m[i][j]) <= e

equalWithRelError(m: V4i, e: int) → bool

Compare two vectors and test if they are “approximately equal”: Return True if the coefficients of this and m are the same with a relative error of no more than e, i.e., for all i, j:

abs (this[i] - v[i][j]) <= e * abs (this[i][j])

dot(v: V4i) → int

Component-wise multiplication by -1

length() → int

Return the Euclidean norm

length2() → int

Return the square of the Euclidean norm, i.e. the dot product with itself.
