Unfortunately it seems that AbsoluteOptions[] applies N[]
to all its output. Tick labels that were not floating-point
numbers will get corrupted.

For example try with

AbsoluteOptions[Plot[Sin[x], {x, 0, Pi}, Ticks -> {{E}, {1/2}}], Ticks]

Any exact numeral in PlotLabel will be affected too.

I sent a report to wri about this in 2003.
