Floor & Ceil (RPN-67 vs Excel)

[dm319]

I think Microsoft Excel has it wrong.

This is what wikipedia says at the bottom of their page:

Wikipedia Wrote:In Microsoft Excel the funtion INT rounds down rather than toward zero,[52] while FLOOR rounds toward zero, the opposite of what "int" and "floor" do in other languages. Since 2010 FLOOR has been changed to error if the number is negative.[53] The OpenDocument file format, as used by OpenOffice.org, Libreoffice and others, INT[54] and FLOOR both do floor, and FLOOR has a third argument to reproduce Excel's earlier behavior.[55]
