Features ==----== Post Processing Filters Comments Variables Error Reporting Base Conversion Constants Operational Modes Parenthesial Support Using Ub3rMath ==----------== 1- Use the included makefile to build the library. You will need cygwin or something similar to build on windows 2- Link your project against libUb3rMath.a and include libUb3rMath.h 4- Use the Ub3rMath class Supported Operators ==---------------== ==- Basic Operators -== + Addition (a + b) - Substraction (a - b) / Division (a / b) * Multiplication (a * b) ^ Exponentiation (a ^ b) % Modulus (a % b) ! Factorial (a !) sqrt Square Root (sqrt a) rt Nth Root (a rt b) log 10th Logarithm (log a) elog Natural Log (elog a) round Round (round a) floor Round Down (floor a) ceil Round Up (ceil a) ==- Geometric Operators -== tan Tangeant (tan a) cos Cosine (cos a) sin Sine (sin a) atan Inverse Tan (atan a) acos Inverse Cos (acos a) asin Inverse Sin (asin a) cotan Cotangeant (cotan a) sec Secant (sec a) cosec Cosecant (cosec a) Post Processing Filters ==-------------------== Filters can be added at the beginning of an equation followed by '<' Example: hex<16 (The output would be 0xf) The following filters are supported: bin binary output (ex: 0b111) hex hexadecimal output (ex: 0bfff) oct octal output (ex: 0o777) cel2far temperature to farenheit far2cel temperature to celcius Variables ==-----== Appending 'x=' to the beginning of an equation (after post processing filters), where x is any alphanumeric character besides 'e' allows you to use variables in subsequent equations. Example: x=5+5 (Outputs 10) 10x (Outputs 100) Error Reporting ==-----------== The following errors are defined, get them with LastError() or LastErrorMessage(): EQUATION_VALID 0x00 No error, use to validate equations UNKNOWN_FILTER 0x01 A filter was called that does not exist INVALID_LEFT_SIDE 0x02 The left side of the equation (x=) was invalid INVALID_NUMBER 0x03 A number was not formatted correctly INVALID_DOT_COUNT 0x04 An integer contained too many dots UNKNOWN_VARIABLE 0x05 A variable used in the equation was not set INVALID_EQUATION 0x06 An illegal character was used in the equation, or symbols were used improperly OPERATOR_INCORRECT 0x07 An operator was not used properly, or one or more of it's operands were missing PARENTHESES_INCORRECT 0x08 Parentheses were not used properly INVALID_ANSWER 0x09 The answer was invalid Base Conversion ==-----------== Numbers of any base can be used easily: 0x-- Hexadecimal 0d-- Decimal 0o-- Octal 0b-- Binary Where -- is a valid number in the specified format Constants ==-----== Some constants are defined and can be called by name: e 2.718281828459045235360287471352 pi 3.141592653589793238462643383279 Operational Modes ==-------------== Using the SetFlags(int flags) method, any combination onf the following can be used: MODE_RADIANS 0x0000 Use radians in calculations MODE_DEGREES 0x1000 Use degrees in calculations MODE_LEFTREM 0x0000 Do not append the left side of the equation to the output (ex: x=) MODE_LEFTAPP 0x0100 Append the left side of the equation to the output (ex: x=) MODE_FIXED Output everything in fixed point notation MODE_FLOAT Output everything in floating point notation MODE_SCI Output everything in scientific notation The default mode is: MODE_RADIANS | MODE_LEFTREM | MODE_FLOAT Parenthesial Support ==----------------== Parentheses can be used in equations to override operator priority Example: 5/5+5 (Outputs 5) 5/(5+5) (Outputs 0.5)
