-    To convert between number bases enter a number (or solve an equation) and change the <link 
xref="number-display">result format</link> from the 
<guiseq><gui>Calculator</gui><gui>Preferences</gui></guiseq> menu.
+    To convert the number to a different base representation use the <em>in</em> operator.
