Build ID: M20070921-1145

Steps To Reproduce:
SlidableAnchor a = new SlidableAnchor(null,new PrecisionPoint(0.1,0.1));
      
PrecisionPoint p = a.parseTerminalString(a.getTerminal());
System.out.println(p.preciseX);
Output is 0.10000000149011612

More information:
If you use double precision and not float precision in BaseSlidableAnchor.parseTerminalString and BaseSlidableAnchor.composeTerminalString then there is no rounding error. Output is 0.1
