Rounding Column Widths

[jonathansampson]

In numerous places, jQuery Columnizer sets widths to Math.floor(100 / numCols) + "%" on generated columns.

Some values don't result in fractions, such as 4 Columns resulting in 25% widths. However, some values do result in fractions, such as three, which results in 33% widths. This does not fully distribute the columns laterally.

Since 33.33333% is a valid value in CSS, why are these values being rounded down?

As I recall, w/o the rounding the last column would sometimes get pushed out and break its float. it wouldn't happen at all widths, and not for all browsers, but did occasionally. it may not be true anymore, originally columnizer was built to run as far back as ie6, so browsers now may handle this much better and not require the rounding.

On the other hand, rounding can break styles:
When last column has border, and container of all columns also has border, it is hard to properly set paddings due to unpredictable width of gap between rightmost borders.

thanks for the pull request, i think that does the right thing by maintain backward compatibility, and also providing flexibility for precision and custom column widths
