Features

Feature overview

• Supported data types: double, integer, complex, boolean, string, array
• Extensible with custom operators (binary, infix or postfix)
• Extensible with custom functions with an arbitrary number of function arguments
• Support for an unlimited number of variables and constants
• No limit on expression complexity
• Reads binary, hexadecimal, complex, integer and string values from expressions and can be extended to read user defined values as well.
• Supports a large variety of predefined Predefined Operators, Predefined Functions and Predefined Constants.
  

Predefined Constants

By default the parser supports the following mathematical constants:

• The eulerian number with:
  e = 2.718281828459045235360287
   
• The mathematical constant equal to a circle's circumference divided by its diameter.
  pi = 3.141592653589793238462643
   
• The imaginary unit with:
  i = sqrt(-1)
   

Predefined Operators

Binary operators:

• Standard operators:
  "+", "-", "*", "/", "^"
   
• Assignment operators:
  "=", "+=", "-=", "*=", "/="
   
• Logical operators:
  "and", "or", "xor","==", "!=", ">", "<", "<=", ">="
   
• Bit manipulation:
  "&", "|", "<<", ">>"
   
• String concatenation:
  "//"
   

Postfix operators:

• Unit postfixes (nano, micro, milli, kilo, giga, mega):
  "{n}", "{mu}", "{m}", "{k}", "{G}", "{M}"
   

Infix operators:

• Sign operator and type conversions:
  "-", "(float)", "(int)"
   

Predefined Functions

• Standard functions:
  abs, sin, cos, tan, sinh, cosh, tanh, ln, log, log10, exp, sqrt
   
• Unlimited number of arguments:
  min, max, sum
   
• String functions:
  str2dbl, strlen, toupper
   
• Complex functions:
  real, imag, conj, arg, norm
