```
    Translates a real into a non-synthesized boolean. It does not push a 0 or a 1 but instead returns branchhandle list to be appended to the false list. A NaN must be converted to "false".
    
    Overrides:
    
    translateToDesynthesized in class Type
    
    See Also:
    
    Type.translateToDesynthesized(org.apache.xalan.xsltc.compiler.util.ClassGenerator, org.apache.xalan.xsltc.compiler.util.MethodGenerator, org.apache.xalan.xsltc.compiler.util.Type)
