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.  
int  base 
Base of parsed numbers. 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. More...  
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 also need to 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 preceeding data set. Default: NULL.  
ParsingMode  parsing_mode 
Parsing mode. Default: PARSING_MODE_ADAPTIVE.  
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 implicite 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".
