Public Attributes | |
| int | min_exp |
| Determines the minimum exponent with scientific notation. Values < -1 restricts the exponent to multiples of -min_exp, e.g. 20 000 is output as 20e3 (engineering notation) if min_exp is -3. The special value EXP_PRECISION (-1) uses the current precision to determine the minimum exponent. Default: EXP_PRECISION. | |
| int | base |
| Number base for displaying numbers. Specify a value between 2 and 36 or use one of the special values defined in includes.h (BASE_*). Default: 10. | |
| BaseDisplay | base_display |
| How prefixes for numbers in non-decimal bases will be displayed. Default: BASE_DISPLAY_NONE. | |
| bool | lower_case_numbers |
| Use lower case for non-numeric characters for bases > 10. Default: false. | |
| bool | lower_case_e |
| Use lower case e for base-10 exponent (ex. 1.2e8 instead of 1.2E8). Default: false. | |
| NumberFractionFormat | number_fraction_format |
| If rational numbers will be displayed with decimals, as a fraction, or something in between. Default: FRACTION_DECIMAL. | |
| bool | indicate_infinite_series |
| Show that the digit series of a number continues forever with three dots, instead of rounding (ex. 2/3 displays as 0.666666... instead of 0.666667). Default: false. | |
| bool | show_ending_zeroes |
| Show ending zeroes for approximate numbers to indicate precision (ex.1.2300000 instead of 1.23) . Default: false. | |
| bool | abbreviate_names |
| Prefer abbreviated names of variables, units, functions etc. Default: true. | |
| bool | use_reference_names |
| Prefer reference names of variables, units, functions etc. Default: false. | |
| bool | place_units_separately |
| Isolate units at the end of the displayed expression (ex. x/y m/s instead of (x m)/(y s)). Default: true. | |
| bool | use_unit_prefixes |
| Use prefixes for units when appropriate. Default: true. | |
| bool | use_prefixes_for_all_units |
| Use prefixes for currencies if unit prefixes are om. Default: false. | |

| Use all decimal SI prefixes. If false, prefixes which is not a multiple of thousand (centi, deci, deka, hekto) will not be used automatically. Default: false. | |
| bool | use_all_prefixes |
| Use prefixes for all units (even imperial and similar ones). Default: false. | |
| bool | use_denominator_prefix |
| If set to true, prefixes will be split between numerator and denominator in a unit expression (millimeter per kilogram instead of micrometer per gram). Default: true. | |
| bool | negative_exponents |
| If true, negative exponents will be used instead of division (ex. 5/x^2 becomes 5*x^-2). Default: false. | |
| bool | short_multiplication |
| Avoid using multiplication sign, when appropriate. Default: true. | |
| bool | limit_implicit_multiplication |
| Use a format compatible with ParseOptions::limit_implicit_multiplication. Default: false. | |
| bool | allow_non_usable |
| If it is not necessary that the displayed expression can be parsed correctly. Default: false. | |
| bool | use_unicode_signs |
| If unicode signs can be displayed. Default: false. | |
| MultiplicationSign | multiplication_sign |
| Sign used for display of multiplication. Default: MULTIPLICATION_SIGN_DOT. | |
| DivisionSign | division_sign |
| Sign used for display of division. Default: DIVISION_SIGN_DIVISION_SLASH. | |
| bool | spacious |
| If space will be used to make the output look nicer. Default: true. | |
| bool | excessive_parenthesis |
| Use parentheses even when not necessary. Default: false. | |
| bool | halfexp_to_sqrt |
| Transform raised to 1/2 to square root and raised to 1/3 to cbrt function. Default: true. | |
| int | min_decimals |
| Minimum number of decimals to display for numbers. Default: 0. | |
| int | max_decimals |
| Maximum number of decimals to display for numbers. A negative value disables the limit. Default: -1. | |
| bool | use_min_decimals |
| Enable use of min_decimals. False is equivalent to a min_decimals value of zero. Default: true. | |
| bool | use_max_decimals |
| Enable use of max_decimals. False is equivalent to a negative max_decimals value. Default: true. | |
| bool | round_halfway_to_even |
| If true round halfway numbers to nearest even number, otherwise round upwards. Default: false. | |
| bool | improve_division_multipliers |
| Multiply numerator and denominator to get integers (ex. (6x+y)/2z instead of (3x+0.5y)/z). Default: true. | |
| Prefix * | prefix |
| Force use of a specific prefix for units if not NULL. Default: NULL. | |
| bool * | is_approximate |
| If not NULL will be set to true if the output is approximate. Default: NULL. | |
| SortOptions | sort_options |
| Options for the order of values in the displayed expression. Default: default_sort_options. | |
| std::string | comma_sign |
| Comma sign or empty string to use default comma sign. Default: empty string. | |
| std::string | decimalpoint_sign |
| Decimal sign or empty string to use default decimal sign. Default: empty string. | |
| bool(* | can_display_unicode_string_function )(const char *, void *) |
| Function that returns true if a text string with unicode signs can be properly displayed. Default: NULL. | |
| void * | can_display_unicode_string_arg |
| Argument passed to can_display_unicode_string_function. Default: NULL. | |
| bool | hide_underscore_spaces |
| Replace underscores in names with spaces, unless name has suffix. Default: false. | |
| bool | preserve_format |
| Preserves the format of the structure (no sorting, no changed prefixes, no improved division multipliers, etc.). Default: false. | |
| bool | allow_factorization |
| Allows factorization to occur in the output (should be set to true if the structure has been factorized). Default: false. | |
| bool | spell_out_logical_operators |
| If logical operators will be spelled as AND and OR instead of && and ||. Default: false. | |
| bool | restrict_to_parent_precision |
| Displays children of the structure with no higher precision than the parent. Default: true. | |
| bool | restrict_fraction_length |
| Restrict the length of numerators and denominator as integers in decimal mode for fractional display of numbers. Default: false. | |
| bool | exp_to_root |
| Transform exponentiation positive base and unit fraction exponent (if denominator < 10) to root function. Default: false. | |
| bool | preserve_precision |
| Use the internal precision of each number instead of global precision. Default: false. | |
