7.13 User Constants.
The variables x, y, and z can have any constant values assigned to
them.
For example, they can be used to denote specific factors frequently used
in your calculations. The variable will then be used instead of a number,
e.g. sqrtx will calculate the square root of this assigned value x. To enter
x, y or z you can either type this character directly into the calculation, or
select the corresponding item from the command menu.
To define a value for the variable x, open command menu item User
constants > x > insert value of calculator line in x, or use shortcut
command 1+B8B9. Such assignments can be helpful if you work
frequently with large numbers.
The following commands are available within command menu item User
constants > x:
1. Insert x into calculation (hotkey: x)
2. Insert value of x into calculator line
3. Insert value of calculator line in x – shortcut command 1+B8B9
4. Show x entry – shortcut 1+B9
This is the same for the variables y respectively z. The corresponding
shortcuts are combined with number 2 respectively number 3.
7.14 Conversions.
The Conversions option and its functions allows various conversions to
be made. For example, how many centimeters are there in 17 inches?
To calculate this, type the number 17 and then open command menu
item Conversion > Inches to centimeters. The correct answer (43.18) will
be displayed in this case.
Note: Answers report back the value only. Symbols relating to the
dimension (inches, centimeters, etc.) are not displayed. The dimension
is defined by the selected conversion command.
