float2::Normalize

Syntax

float float2::Normalize(); [16 lines of code]

Normalizes this float2.

In the case of failure, this vector is set to (1, 0), so calling this function will never result in an unnormalized vector.

Note
If this function fails to normalize the vector, no error message is printed, the vector is set to (1,0) and an error code 0 is returned. This is different than the behavior of the Normalized() function, which prints an error if normalization fails. This function operates in-place.

Return Value

The old length of this vector, or 0 if normalization failed.
