Public Attributes | |
| ApproximationMode | approximation |
| How exact the result must be. Default: TRY_EXACT. | |
| bool | sync_units |
| If units will be synced/converted to allow evaluation (ex. 1 min + 1 s=60 s+ 1 s = 61 s). Default: true. | |
| bool | sync_nonlinear_unit_relations |
| If units with complex/non-linear relations (ex. degrees Celsius and Fahrenheit) will synced/converted. Default: true. | |
| bool | keep_prefixes |
| If unit prefixes in original expression will be kept. Default: false. | |
| bool | calculate_variables |
| If known variables will be replaced by their value. Default: true. | |
| bool | calculate_functions |
| If functions will be calculated. Default: true. | |
| int | test_comparisons |
| If comparisons will be evaluated (ex. 5>2 => 1). Default: true. | |
| bool | isolate_x |
| If a variable will be isolated to the left side in equations/comparisons (ex. x+y=2 => x=2-y). Default: true. | |
| int | expand |
| If factors (and bases) containing addition will be expanded (ex. z(x+y)=zx+zy). Default: true. | |
| bool | combine_divisions |
| Use behaviour from version <= 0.9.12 which returns (x+y)/z instead of x/y+y/z if expand = true. | |
| bool | reduce_divisions |
| If non-numerical parts of a fraction will be reduced (ex. (5x)/(3xy) =5/(3y) . Default: true. | |
| bool | allow_complex |
| If complex numbers will be used for evaluation. Default: true. | |
| bool | allow_infinite |
| If infinite numbers will be used for evaluation. Default: true. | |
| int | assume_denominators_nonzero |
| If simplification will be made easier by assuming that denominators with unknown value not is zero. Default: false. | |
| bool | warn_about_denominators_assumed_nonzero |
| Warn if a denominator with unknown value was assumed non-zero (with assume_denominators_nonzero set to true) to allow simplification. Default: true. | |
| bool | split_squares |
| If powers with exponent 1/2 that only have an approximate result will be split to the least base (sqrt(8) = 2 * sqrt(2)). Default: true. | |
| bool | keep_zero_units |
| If units with zero quantity will be preserved. Default: true. | |
| AutoPostConversion | auto_post_conversion |
| If and how units will be automatically converted. Does not affect syncing of units. Default: POST_CONVERSION_OPTIMAL. | |
| MixedUnitsConversion | mixed_units_conversion |
| Shows time as h + min + s, imperial length as ft + in, etc. Default: MIXED_UNITS_CONVERSION_DEFAULT. | |
| StructuringMode | structuring |
| If the evaluation result will be expanded or factorized Default: STRUCTURING_NONE. | |
| ParseOptions | parse_options |
| Options for parsing of expression. Default: default_parse_options. | |
| const MathStructure * | isolate_var |
| If set will decide which variable to isolate in an equation. Default: NULL. | |
| bool | do_polynomial_division |
| Use polynomial division to simplify the result. Default: true. | |
| MathFunction * | protected_function |
| Do not calculate the specified function. Default: NULL. | |
| ComplexNumberForm | complex_number_form |
| Complex number form. Default: COMPLEX_NUMBER_FORM_RECTANGULAR. | |
| bool | local_currency_conversion |
| Convert to local currency when optimal conversion is enabled. | |
| bool | transform_trigonometric_functions |
| Mainly for internal use. Default: true. | |
| IntervalCalculation | interval_calculation |
| Algorithm used for calculation of uncertainty propagation / intervals. This does not affect calculation of the high precision intervals produced by approximate functions or irrational numbers. Default: INTERVAL_CALCULATION_VARIANCE_FORMULA. | |
