Let me illustrate with one simple example:
Let A and B be two given poinst where we have access to their coordinates, say
A = (\xA,\yA)and
B = (\xB,\yB).
I would then like to be able to check if A = B within some tolerance.
But how should I test to see, say, for
\dx = \xB-\xAthat
abs(\dx) < \epsfor a small defined value of
As far as I know the Latex
\ifthenelsecannot be used.
