# List of TeX commands for Generic Problems¶

TODO - Work in progress.

Default value is the value that the command will get when it is omitted from the TeX file.

TeX-Command Description
\correctorprecision{<number>} Default value: 2
defines the amount of digits that will be used behind the decimal mark, indicated by <number>, when correcting the final answer of the student.
\displayprecision{<number>} Default value: 2
defines the amount of digits that will be visible behind the decimal mark, indicated by <number>, when displaying the number on the screen. Numbers defined through \randdouble are rounded to the same number of digits behind the decimal mark. Typically the displayprecision $\ge$ correctorprecision. Displayprecision only affects variables of type \randdouble, results of calculated functions will always display the full double value, unless the command below is used.
\function[calculate, <number>]{<var>}{<expression>} Default value: 16
Will calculate the <expression> and round the result according to the value of <number>. The option <number>, should only be used when you want to display the result of the calculated function on the screen. If <number> is not provided calculate will result in a number with an accuracy of up to 16 digits behind the decimal mark.
