Mounted line duration was utilized by some early mainframe running methods. In this kind of method, an implicit end-of-line was assumed each 72 or eighty figures, as an example. No newline character was saved. If a file was imported from the outside entire world, strains shorter than the line length had to be padded with Areas, when strains more time than the line length needed to be truncated. This mimicked using punched playing cards, on which Every line was saved on the different card, usually with 80 columns on Each individual card, generally with sequence figures in columns seventy three–80.

Much more specifically, given a basket of shares, there exists a notion of the economical frontier. I.e., for just about any return you select, there exists a portfolio with the bottom variance and for just about any variance you fix, there exists a portfolio with the best return. Any portfolio you decide on that's not on this effective frontier is considered sub-optimum (for the provided return, why would you end up picking a a greater variance portfolio any time a decreased one exists).
In some languages the symbol utilized is considered to be an operator (which means that the assignment has a price) while others determine the assignment as a press release (indicating that it can't be Employed in an expression).
