iText, PageSize A4 - units

I'm creating document in iText. I need custom width however when it's smaller than A4 standard width, it should be set to A4 standard width.

So I got:

float pageWidth = columns.size() * 100;
if (pageWidth < PageSize.A4.getWidth()) {
       pageWidth = PageSize.A4.getWidth();
}
table.setTotalWidth(pageWidth);

And it's not working, probably because pageWidth and PageSize.A4.getWidth() got different units. When I debugged this, I got 900.0 value in pageWidth and PageSize.A4.getWidth() returns 595.0 So what do I need to change to get same units for comparison?

900 is not lower than 595, so pageWidth<PageSize.A4.getWidth() is not true, and this is never executed: pageWidth = PageSize.A4.getWidth();

The value of pageWidth never changes. You have 9 colums. You multiply with 100 and that results in 900. 900 is bigger than 595, so pageWidth remains 900.

I think you want the opposite of what you're asking:

float pageWidth = columns.size()*100;
if(pageWidth > PageSize.A4.getWidth()){
   pageWidth = PageSize.A4.getWidth();
 }
table.setTotalWidth(pageWidth);

Now, when pageWidth doesn't fit he page, it will be reduced to 595.

I think you made a logical error that is totally unrelated to iText.
