Chapter 12. Settings
To configure Genius Mathematics Tool, choose ->. 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 Section 5.2 about evaluating and assigning to variables, and Section 10.3 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: MaxDigits = 12 |
12.1. 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)- Use mixed fractions
If fractions should be printed as mixed fractions such as "1 1/3" rather than "4/3". (
MixedFractions)- Remember output settings across sessions
Should the output settings in the Number/Expression output options frame be remembered for next session. Does not apply to the Error/Info output options frame.
If unchecked, either the default or any previously saved settings are used each time Genius starts up. Note that settings are saved at the end of the session, so if you wish to change the defaults check this box, restart genius and then uncheck it again.
- 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 Section 10.3.
IntegerOutputBaseThe base that will be used to output integers
OutputStyleA 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
