57.1 | 1 | If an ONYX variable is used in MAXIMA calculations, it is always recommended to enclose it with parentheses (⋅). |

19.1 | 2 | |

57.1 | 3 | Example: Variable {a} squared: |

19.1 | 4 | |

57.1 | 5 | If {a}=-5 then {a}^2=-5^2=-25, whereas ({a})^2=(-5)^2=25. |

| 7 | The comparison of the two variants – with and without parentheses – can be seen in the example image below. | ||

| 11 | ONYX connects the CAS MAXIMA as an external application. MAXIMA requests are sent to MAXIMA in a form defined by the user without being interpreted or modified. If you choose a numeric data type as the variable and thus as the result data type, only the float expression will be added. | ||

| 13 | If it is intended that {var1} can assume any value of the user, then "3+4" or any other expression is also conceivable. If {var1} is now used in a MAXIMA request, e. g. {var1}^2, this is inserted corresponding to a placeholder without further intervention and transmitted to MAXIMA for calculation. Therefore, to preserve the intended overall context, additional parentheses around ONYX variables are necessary. |
