| float2::LengthSqSyntaxfloat float2::LengthSq() const; [4 lines of code]Computes the squared length of this vector. Calling this function is faster than calling [Length()], since this function avoids computing a square root. If you only need to compare lengths to each other, but are not interested in the actual length values, you can compare by using [LengthSq()], instead of [Length()], since [Sqrt()] is an order-preserving (monotonous and non-decreasing) function. Return Valuex*x + y*y. See Also LengthSq(), Distance(), DistanceSq(). |
