[sv-bc] RE: Mantis 1523

Shalom,

That particular sentence defined the semantics of the ternary operator when it needs to merge two objects of non-integral data-type, such as real or string. Since in those cases performing a bit-wise resolution is not possible (or well defined), the LRM calls for comparing the two elements (using equality) and return the default-uninitialized value if they do not "match". Possibly a better language would be "if the elements are not equal".
