#include <includes.h>
Public Attributes  
bool  variables_enabled 
If variables will be parsed. Default: true.  
bool  functions_enabled 
If functions will be parsed. Default: true.  
bool  unknowns_enabled 
If leftover characters will be parsed as symbols. Default: true.  
bool  units_enabled 
If units will be parsed. Default: true.  
bool  rpn 
If Reverse Polish Notation syntax will be used. Default: false (deprecated, use parsing_mode = PARSING_MODE_RPN instead)  
int  base 
Base of parsed numbers. Specify a value between 2 and 36 or use one of the special values defined in includes.h (BASE_*). Default: 10.  
bool  limit_implicit_multiplication 
When implicit multiplication is limited variables, functions and units must be separated by a space, operator or parenthesis ("xy" does not equal "x * y"). Default: false.  
ReadPrecisionMode  read_precision 
If and when precisions will be read from number of digits in a number. Default: DONT_READ_PRECISION.  
bool  dot_as_separator 
If true dots will ignored if another character is the default decimal sign, to allow dots to be used as thousand separator. Default: false.  
bool  comma_as_separator 
If true commas will ignored if another character is the default decimal sign, to allow commas to be used as thousand separator. You should also call CALCULATOR>useDecimalPoint(true). Default: false.  
bool  brackets_as_parentheses 
Interpret square brackets equally to parentheses (not only for vectors/matrices). Default; false.  
AngleUnit  angle_unit 
Default angle unit for trigonometric functions. Default: ANGLE_UNIT_NONE.  
MathStructure *  unended_function 
If nonNULL will be set to unfinished function at the end of the expression (if there is one). Default: NULL.  
bool  preserve_format 
Preserve the expression structure as much as possible. Default: false.  
DataSet *  default_dataset 
Default dataset. Used for object.property syntax without a preceding data set. Default: NULL.  
ParsingMode  parsing_mode 
Parsing mode. Default: PARSING_MODE_ADAPTIVE.  
bool  twos_complement 
Negative binary numbers uses two's complement representation. All binary numbers starting with 1 are assumed to be negative, unless binary_bits is set. Default: false.  
bool  hexadecimal_twos_complement 
Negative hexadecimal numbers uses two's complement representation. All hexadecimal numbers starting with 8 or higher are assumed to be negative, unless binary_bits is set. Default: false.  
unsigned int  binary_bits 
Number of bits used for binary and hexadecimal numbers. Set to 0 for automatic. Default: 0.  
Options for parsing expressions.
bool ParseOptions::limit_implicit_multiplication 
When implicit multiplication is limited variables, functions and units must be separated by a space, operator or parenthesis ("xy" does not equal "x * y"). Default: false.
If the limit implicit multiplication mode is activated, the use of implicit multiplication when parsing expressions and displaying results will be limited to avoid confusion. For example, if this mode is not activated and "integrte(5x)" is accidently typed instead of "integrate(5x)", the expression is interpreted as "int(e * e * (5 * x) * gr * t)". If limit implicit multiplication is turned on to mistyped expression would instead show an error telling that "integrte" is not a valid variable, function or unit (unless unknowns is not enabled in which case the result will be "5 'integrate' * x".
