# Formúla

Opens a submenu, from which you can insert a formula into the cell of a table. Place the cursor in a cell in the table or at the position in the document where you want the result to appear. Click the Formula icon and choose the desired formula from the submenu.

The formula appears in the input line. To specify a range of cells in a table, select the desired cells with the mouse. The corresponding cell references also appear in the input line. Enter additional parameters, as necessary, and click Apply to confirm your entry. You can also enter the formula directly if you know the appropriate syntax. This is necessary, for example, in the Insert Fields and Edit Fields dialogs.

### Aðgerðir

You can insert various operators in your formula. Choose from the following functions:

 Listaskiltákn | Separates the elements in a list. Example of using a list: MIN 10|20|50|||20 Líkt EQ or == Checks if selected values are equal. If they are unequal, the result is zero, otherwise 1 (true) appears. Example: EQ 2 displays 1, if the content of A1 equals 2. Ekki jafnt NEQ or != Tests for inequality between selected values. Example: NEQ 2 displays 0 (wrong), if the content of A1 equals 2. Minna en eða jafnt og LEQ Tests for values less than or equal to a specified value. Example: LEQ 2 displays 1 (true), if the content of A1 is less than or equal to 2. Stærra en eða jafnt og GEQ Tests for values greater than or equal to a specified value Example: GEQ 2 displays 1 (true), if the content of A1 is greater than or equal to 2. Minna L Tests for values less than a specified value Example: L 2 displays 1 (true), if the content of A1 is less than 2. Meira en G Tests for values greater than a specified value Example: G 2 displays 1 (true), if the content of A1 is greater than 2. Boole gildið EÐA EÐA Tests for values matching the Boolean OR Example: 0 OR 0 displays 0 (false), anything else results in 1 (true) Boole gildið EÐA XOR Tests for values matching the Boolean exclusive OR Example: 1 XOR 0 displays 1 (true) Boole gildið OG OG Tests for values matching the Boolean AND Example: 1 AND 2 displays 1 (true) Boole gildið EKKI NOT Tests for values matching the Boolean NOT Example: NOT 1 (true) displays 0 (false)
