It doesn't make much sense, right? I suppose it's there for a clean implementation of operators in C. While the unary minus returns the negative of the operand the unary plus returns the value to avoid ambiguity, i.e. shall the unary plus return the positive of a negative operand, as the unary minus does? IMHO, not a result I'd expect. \Steve - : send the line "unsubscribe linux-c-programming" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
