OK, I get it - you copied a function that did 75% of what you want to accomplish and updated it to do your evil bidding.

But why then did you keep the original function comment???

it would be as if you had the code....

// Sometimes we need have someone else multiply radius by two
bool getDiameterFromRadius(float radius, double & rDiameter) { ... }

And somebody copied the function to do something else....

// Sometimes we need have someone else multiply radius by two
bool getCircumferenceFromRadius(float radius, double & rCircumference) { ... }

AND LEFT THE SAME COMMENT IN PLACE.

.ugh.
