Settings
To configure Genius Math Tool, choose Settings->Preferences. There are several basic parameters provided by the calculator in addition to the ones provided by the standard library. These control how the calculator behaves.

Many of the settings in Genius are simply global variables, and can be evaluated and assigned to in the same way as normal variables. See the Section called Using Variables in the chapter called GEL Basics about evaluating and assigning to variables, and the Section called Parameters in the chapter called List of GEL functions for a list of settings that can be modified in this way. As an example, you can set the maximum number of digits in a result to 12 by typing:

Output
- Maximum digits to output
The maximum digits in a result (MaxDigits)
- Results as floats
If the results should be always printed as floats (ResultsAsFloats)
- Floats in scientific notation
If floats should be in scientific notation (ScientificNotation)
- Always print full expressions
Should we print out full expressions for non-numeric return values (longer than a line) (FullExpressions)
- Display errors in a dialog
If set the errors will be displayed in a seprate dialog, if unset the errors will be printed on the console.
- Display information messages in a dialog
If set the information messages will be displayed in a seprate dialog, if unset the information messages will be printed on the console.
- Maximum errors to display
The maximum number of errors to return on one evaluation (MaxErrors). If you set this to 0 then all errors are always returned. Usually if some loop causes many errors, then it is unlikely that you will be able to make sense out of more than a few of these, so seeing a long list of errors is usually not helpful.
In addition to these preferences, there are some preferences that can only be changed by setting them in the workspace console. For others that may affect the output see the Section called Parameters in the chapter called List of GEL functions.
- MixedFractions
If fractions should be printed as mixed fractions such as "1 1/3" rather than "4/3"
- IntegerOutputBase
The base that will be used to output integers
- OutputStyle
A string, can be "normal", "latex", "mathml" or "troff" and it will effect how matrices (and perhaps other stuff) is printed, useful for pasting into documents
