Operation | Description |
---|---|
MFloatVector = MFloatVector ^ MFloatVector | Cross product of two vectors. |
float = MFloatVector * MFloatVector | Dot product of the two vectors. |
MFloatVector = MFloatVector / scalar | Returns a new vector whose components are those of the given vector, each divided by scalar, which can be of any type which is convertable to float. |
MFloatVector /= scalar | Divides each component of the vector by scalar, which can be of any type which is convertable to float, and returns a new reference to the vector. |
MFloatVector = MFloatVector * scalar | Returns a new vector whose components are those of the given vector, each multiplied by scalar, which can be of any type which is convertable to float. |
MFloatVector = scalar * MFloatVector | Returns a new vector whose components are those of the given vector, each multiplied by scalar, which can be of any type which is convertable to float. |
MFloatVector *= scalar | Multiplies each component of the vector by scalar, which can be of any type which is convertable to float, and returns a new reference to the vector. |
MFloatVector = MFloatVector * MFloatMatrix | Postmultiplying a vector by a matrix. |
MFloatVector = MFloatMatrix * MFloatVector | Premultiplying a vector by a matrix. |
MFloatVector *= MFloatMatrix | Postmultiplies the vector by the matrix and returns a new reference to the vector. |

MFloatVector = -MFloatVector | Negate a vector. |
MFloatVector = MFloatVector - MFloatVector | Vector subtraction. |
MFloatVector -= MFloatVector | In-place vector subtraction. |
MFloatVector == MFloatVector | Returns True if each component of the first vector is exactly equal to the corresponding component of the second. |
MFloatVector != MFloatVector | Returns False is any component of the first vector is not exactly equal to the corresponding component of the second. |
All other comparison operators will raise a TypeError exception.
