=====cVector2f=====

====Fields====

^ Field Name ^ Type ^ Description ^
| x | float | The x value of the vector. |
| y | float | The y value of the vector. |

====Functions====

^ Return Type ^ Function Name ^ Parameters ^ Description ^
| float | GetElement | uint64 alIdx, \\ const | Gets the value at the given index. (Indices 0 and 1 are equal to x and y, respectively.) |
| void | SetElement | uint64 alIdx, \\ float afVal, \\ const | Sets the value at the given index to the given value. (Indices 0 and 1 are equal to x and y, respectively.) |
| float | SqrLength | const | Returns the length-squared of this vector. |
| float | Length | const | Returns the length of this vector. |
| float | Normalize |     | Returns the normalization factor for this vector. (See Remarks.) |

====Remarks====

A normalized vector is a vector whose length is equal to one, otherwise known as a unit vector. To convert a vector into a unit vector, get the normalization factor by calling the ''Normalize'' function, then divide each of the vector's x and y coordinates by that factor.

<code=c++>cVector2f vBaseVector(2.0, 5.0);
float fNormFactor = vBaseVector.Normalize();
cVector2f vNormalizedVector(vBaseVector.x / fNormFactor, 
                            vBaseVector.y / fNormFactor);</code>
