#Openoffice space code

The braces to group must be closed on each line.

It is important to note that the braces, as well as the brackets, needs to be closed: with only a left brace or a right brace Math will display an error.īraces and brackets must be closed on the same line: it is not possible to insert a newline command between two brackets. The braces are used to group elements on an equation. The first one will give while the second will give.

The reader can check the result of the following line of code on a Math objectĬompare the result of the following expressions The first one turns the following element into an unary operator while the second turns the element to a binary operator. For example, the operators from and to can be used to insert limits on operatorsĪ particular operator is 'nospace': this operator reduce the horizontal space between two elements, as it is possible to see on the following screen shotįinally, there are two operators that can be used to turn any element into an operator: oper and boper. Some operators modify the output of other operators. Other examples the sum operator, the integral (int), close integral (oint), etc.Īs commented above, binary operators need two elements. Writing on a Math object the command over without any other text, only a red question mark will be obtained: the command over is a binary operator that needs two objects (numerator and denominator of the fraction) to work. On the preview a placeholder shows as a box with a shadow. This is a 'placeholder' used to avoid errors for missing arguments and can be replaced with the needed content.

When inserting operators from the contextual menu or the Elements window, the following structure will be introduced too There are also instructions that need the use of parameters to define their action, for example the command 'color' This second command can be used to put the arrow over more than one element, to obtain for example

For example, the 'decorations' like a vector arrow: Some commands need to be applied to other objects because alone do not have sense. With a right click on the Math editor area, you have access to an organized list with all available commands.
