Normalizing from [0.5 - 1] to [0 - 1]

Question

I\'m kind of stuck here, I guess it\'s a bit of a brain teaser. If I have numbers in the range between 0.5 to 1 how can I normalize it to be between 0 to 1?

Thanks for a

Lazyweb answer: To convert a value x from [minimum..maximum] to [floor..ceil]:

General case:

normalized_x = ((ceil - floor) * (x - minimum))/(maximum - minimum) + floor

To normalize to [0..255]:

normalized_x = (255 * (x - minimum))/(maximum - minimum)

To normalize to [0..1]:

normalized_x = (x - minimum)/(maximum - minimum)
