Public Member Functions
const string &	comma () const
	Returns the comma sign used (default sign or comma_sign)

const string &	decimalpoint () const
	Returns the decimal sign used (default sign or decimalpoint_sign)

Public Attributes
int	min_exp

int	base
	Number base for displaying numbers. Default: 10.

BaseDisplay	base_display
	How prefixes for numbers in non-decimal bases will be displayed.

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.

bool	use_prefixes_for_currencies
	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 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.

string	comma_sign
	Comma sign or empty string to use default comma sign. Default: empty string.

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.
