Is there a way to align numbers in a TikZ matrix at the decimal points, as is possible in normal tables (Aligning numbers by decimal points in table columns)?
http://www.texample.net/tikz/builds/ says that a feature that "Added '/pgf/number format/assume math mode' to disable math checks. This allows to assemble tabulars, apply pgfmathprintnumber to each cell and use the dcolumn package to align at decimal separators (no documentation for that feature yet)" was made in June of 2008, but nothing else.

s, not pgf matrices. – Matthew Leingang Dec 31 '10 at 5:21
