There are three buttons to the right of the expression entry and the result display. The upper button performs calculation of the entered expression (same as <keycap>Enter</keycap>), the one below saves the current result as a variable (see <xref linkend="qalculate-variable-creation"/>), while the last button opens a dialog for conversion of units in the result (see <xref linkend="qalculate-unit-conversion"/>). When non-default options for the interpretion of expressions have been selected, the choice will be indicated in a small status area below the expression entry, to the right. +</para> +</sect1> +<sect1 id="qalculate-expression-entry"> +<title>Expression Entry</title> +<para> +The expression entry is the most important part of the Qalculate! user interface. The normal calculation procedure in Qalculate! is to type in a mathematical expression (ex. <quote>5+5</quote>) and press <keycap>Enter</keycap> (or click <guibutton>Execute</guibutton>). The result (<quote>10</quote>) is then displayed below the expression entry in the result display. +</para> +<figure id="qalculate-FIG-completion"> + <title>Completion</title> + <screenshot> + <mediaobject> + <imageobject> + <imagedata fileref="completion.png" format="PNG"/> + </imageobject> + </mediaobject> + </screenshot> +</figure> +<para> +Qalculate! helps out with the expression by giving a list of possible endings to words representing functions, variables and units. The list will narrow with each letter typed. Select an item in the list and the name will be completed. If a function was selected, parenthesis will be added and the position moved for immediate entry of arguments. +</para> +<para> +As the expression is typed in, the area directly direclty below the expression entry, to the left, will show useful information. By default the calculator's interpretation of the expression is shown (ex. <quote>5 * meter</quote> for <quote>5m</quote>). The interpretation will be displayed in red (configurable) if there are errors in the expression or in blue for lesser errors (for example too many arguments in a function). If the last typed in text represents a function, and arguments are about to be entered, the functions name and its arguments will be displayed. The first argument in the information text is highlighted and includes information about its type and restrictions and when an argument has been entered, the next will be highlighted. +</para> +<para> +After execution of an expression, the whole expression will be marked. This normally means that if something new is entered, the old expression will be overwritten. If, however, an operator (+, −, *, /, ^) is entered first, the old expression will instead be the target of action. The operator will then apply to the whole expression, which is put in parenthesis. This works on all marked ranges, meaning that this way an expression can conveniently be put in parenthesis. Functions set the selection as their first argument. +</para> +<para> +The <keycap>Up</keycap> and <keycap>Down</keycap> keys will access previously entered expressions. With focus in the expression entry, <keycap>Up</keycap> traverses backwards in the expression history and <keycap>Down</keycap> forward. +</para> +<para> +The font used for the expression entry can be selected in the preferences dialog (<menuchoice><guimenu>Edit</guimenu><guimenuitem>Configure Qalculate!</guimenuitem></menuchoice>). +</para> +</sect1> +<sect1 id="qalculate-result-display"> +<title>Result Display</title> +<para> +The result of calculations is displayed in the open area below the expression entry. The font used for the result display can be selected in the preferences dialog (<menuchoice><guimenu>Edit</guimenu><guimenuitem>Configure Qalculate!</guimenuitem></menuchoice>). Use of Unicode signs can be turned off in the same dialog. Otherwise Qalculate! will try to make the result as fancy as possible and print π for pi, √ for sqrt, € for euro, and so on. Information about customization of the mathematical result output is available in <xref linkend="qalculate-result"/>. +</para> +<para> +In front of the result an equals or approximately equals sign is shown. This indicates whether Qalculate! was able to calculate/display the result exact or only approximate, in the current mode. +</para> +<para> +The result display has a context menu, which pops up when clicking with the right mouse button anywhere in the field. This menu provides a subset of the display alternatives from the mode menu (<xref linkend="qalculate-TBL-mode-menu"/>) and some actions from the edit menu (<xref linkend="qalculate-TBL-edit-menu"/>).

This will only work if you have tooltips enabled in KDE. You can also show this information by double clicking or selecting <guimenuitem>Show Object Info</guimenuitem> in the context menu.

The stack has a variable number of registers which can hold an unlimited number of values. The stack size is dynamically changed when a new value is added and the first value on the stack is shown in the result display. Mathematical operators such as plus and minus then operates on the first two, last added, values on the stack. The second value is changed with input from the first value. For example, the minus operator subtracts the first value from the second. Functions which require exactly one argument operates on the first value on the stack. Other functions, which require multiple arguments, must be entered in normal expression based way. +</para> +<para> +The RPN mode still allows full expression to be entered (you can add <quote>5x+3+23+sin(2)</quote> directly to the stack). The buttons on the keypad do not insert operators and functions in the expression entry, but instead applies them to the stack. This is also true for the keypad keys on the keyboard. <keycap>Enter</keycap> calculates the current expressions and adds it to the stack. If the expression entry is not empty when applying an operator or function to the stack, the expression is first calculated and added to the stack. All keys on the main part of the keyboard add the corresponding characters in expression entry, unless the <guilabel>Use only keypad keys for RPN</guilabel> option is deactivated from the preferences dialog. To apply the raise operator '^' to the stack, without clicking the keypad button with the mouse, use the <keycombo><keycap>Ctrl</keycap><keycap>* (keypad)</keycap></keycombo> shortcut. If the expression only contains an operator or a function, which requires exactly one argument, the operator/function is applied to the stack. +</para> +<para> +For example, <command>5 ENTER 3 + 2 /</command> adds 5 to the stack, then adds 3 to the stack and moves 5 down a step and adds 3 to 5. The first value, 3, is removed from the stack and the value left is 8. Then 2 is added to the stack and 8 is divided by 2, resulting in 4.

These placeholders consists of a backslash and a letter — x, y, z for the 1st, 2nd and 3rd arguments and a to u for argument 4 to 24. They are replaced by entered arguments when a function is calculated. The placeholders naturally also decide the number of arguments that a function requires. For example the function for triangle area (<quote>base * height / 2</quote>) has the name triangle and the expression <quote>(\x*\y)/2</quote>, which gives that <quote>triangle(2, 3)</quote> equals <quote>(2*3) / 2</quote> and returns <quote>3</quote> as result.

Base units are units defined as basis for other units. Meters and seconds are typical base units. Alias units is defined in relation to another unit. For example, hour is defined as an alias unit that equals 60 minutes which in turn is defined in relation to seconds. Finally, composite units are defined by a unit expression with multiple units. Composite units often have an alias unit associated with them, as they do not have a reference name on their own.

Depending on the unit class, different elements in the dialog will be enabled. For all units, category and descriptive name can be specified to keep them well organized. A unit can also be hidden from unit menus with the corresponding check box, which can be useful for some composite units. +</para> +<para> +Base and alias units normally have three different name forms defined for use in expressions — abbreviation (ex. <quote>m</quote>), singular (<quote>meter</quote>) and plural (<quote>meters</quote>). Composite units only have an internal name, used to reference the unit in definitions of other units. +</para> +<para> +For base units, the name is all that is needed. For alias units, on the other hand, a base unit, exponent and relation are necessary. For more complex relations an inverse relation can also be specified for conversion back from the base unit. The base unit must not necessarily be of the base unit class and it is recommended that an alias unit is defined in relation to the closest unit (ex. 1ft = 3 hands, 1 hand = 4 in, and 1 in = 0.0254 m). The relation is usually just a number that tells how large quantity of the base unit is needed to get the alias unit (alias unit = base unit * relation). More complex units can specify the relation as a full-blown expression where <quote>\x</quote> is replaced by the quantity of the base unit and <quote>\y</quote> is the exponent. For example, Degrees Celsius has the relation <quote>\x + 273.15</quote> and the inverse relation <quote>\x − 273.15</quote> to the base unit Kelvin. For simple relations, the reversion is automatic and ought not be defined separately. The check box below relation in the dialog specifies if the relation is exact or approximate. The exponent defines the exponential relation to the base unit, so that the alias unit equals the base unit raised to the exponent. For simple unit relations this gives: alias unit = relation * base unit^exponent. +</para> +<para> +Composite units need a unit expression with multiple units as base, in the base unit field.
