public class GEExpression

extends BinaryExpression

The GEExpression class implements the semantic node for "greater or equal". The binOp method calculates for both Integer and Float by contagion. If either object is a Float then the whole expression will be a Float. Otherwise it will be an Integer. (Eventually these aritmetic semantic nodes will accomodate Double and Long and Short as well.)
