Subject: Move to double to avoid rounding error

This rounding errors seems to happen when adding floats very close to 1
to a relatively large number.

325.0 + 0.99999034 = 326.0

This is a problem as this sample should be counted at the 325 pixel.
However this will be a lesser problem when filtering is implemented.
